You can make your own MOSFET switch with components, wire, and a soldering gun. However, they do not have the same connective capabilities as their advanced counterparts (like Bluetooth). Without it, we get major arc burns, rendering the trigger switch useless after only a couple dozen pulls.

I'm betting on gate fail from RF spikes. the schematic below shows common use of a mosfet to drive a motor. The MOSFET setup is pretty simple. If the threshold voltage can be as high as 4V, that means the device is fully off below 4V. The actual voltages vary significantly between lots due to manufacturing spread too, so its best not to push your luck.

Is there a safer way to go about protecting the chip while still providing adequate cooling? When the trigger is pulled, the electrical current flows through all three parts of the circuit - trigger, battery, motor. Lots of questions hereor maybe it's just ignorance. Try a 12 volt 1 watt zener diode from the gate to source to stop any RF spikes that are coming from the motor. Perhaps contact bounce in the switch is causing that effect to happen; hence the FET frying. Why would power in the diode make the FET get hot? All of these features contribute to the electrical efficiency of the gun, improve battery life (causing a single battery charge to last longer during airsoft games), and increase the gun's durability. We are currently working on the project steps, so check back soon if you are interesting in wiring up your own MOSFET unit. I share your concern about slowing the gate charge/discharge, which C1 would definitely do. We make great efforts to maintain reliable information on all airsoft and tactical products presented on High Speed BBs. Typical threshold voltages for logic level FETs are 0.51.0V. it looks like you're diagram is correct. Can you describe the different types of diodes for me? Use code FREESHIP for free standard shipping on orders over $300, please note that all delivery dates are estimates only. if the mosfet is connected between the motor and ground, the drain is ~1V above ground. The surge measurement is an estimate based on a computerized multimeter a friend of mine has. Free Shipping on orders over $300! gcjr: so i can get it to turn on and off with a delay with this code: but it keeps going when the button is pressed, Powered by Discourse, best viewed with JavaScript enabled. Please read the rules, Wiki/FAQ, and use the search bar! it was more on than off). Knowing what I know about the parts involved, this makes perfect sense. VDS =VGS;ID =250A <<<<<< next to nothing for Drain current 250A. 2022 HighSpeed BBs. The first part to understanding MOSFETs is learning what it is and what it does. on the other had, if the mosfet were between the supply voltage (e.g. The trouble is that its having trouble when the gate voltage is coming and going during the spike to get the motor going, when it is taking 100-200 amps. with 2 switches For an airsoft RIF, so i want to press say switch one to make the motor do spin once. 
wondering how you did to "fryed" them. i had never heard of a logic level mosfet. 
I have a dead graphics card I can salvage parts from, I Googled airsoft mosfet schematic and got this, http://unconventional-airsoft.com/2009/08/26/how-to-make-a-basic-mosfet-switch/. i used a mtb40b10e (40A 100V) to drive a small 12V DC motor and it seemed to work with the gate at 5V (i.e. Click Enter only if you are at least 18 years of age. VGS =10V;ID = 40A <<<<<< this requires 10v to get the stated resistance. Go by the power dissipation being I-squared-Ron. the datasheet for the STP80NE06-10 specifies that its gate threshold voltage (Vgs) is between 2-4 V. seems like it should work in most cases with a 5V output. Learn more. The mosfet connects the motor to ground. Here's another way to look at it. A logic-level MOSFET is designed to be fully on with only 5V or so. Brand Disclosure: Product names, logos, brands, and other trademarks featured or referred to within our content and website are the intellectual property of their respective trademark holders. Let's talk about MOSFET's and their uses in guns. how would i go about controlling this with an arduino, i have tried to make a mosfet myself and it kindof worked but i was frying them , so i want to use this pre made one. The MOSFET unit is pretty much an electrical switch attached to your AEG airsoft gun's wiring. No way can it be fully on at 4.5V if thats the case. This is a very powerful gun, hence the need for the MOSFET in the first place. (diode?). Any reference in this website to third party trademarks, brands, or logos is to identify the corresponding third party goods and/or services. the chart above indicates it can pass 10A at 5V. The battery is an 11.1V 2200mAh 30C LiPo hobby battery. No way can it be fully on at 4.5V if that's the case. 12V) and the motor and the gate set to the supply voltage, then the source would be slightly below the supply voltage. Gate Threshold Voltage the diode across the motor provides a path for current when motor is turned off. mosfet resistance is often measured in milliOhm, meaning that a mosfet needs to dissipate very little power when passing relatively large currents. ClassicArmy M133 With 4 Tracers what do you guys think Cry all you want, it won't remove the carry handle from NFTs arrive to airsoft extremely late to the party. You could be having gate fail taking out the FET. Yes it can handle 40 amps no problem. this is all very interesting and I understand that there are subtleties to this that I don't understand. Two wires from the motor to the mosfets will help balance the current because the wires have a little bit of resistance in them. assuming my numbers are correct, what do I need to do to make the system work? Won't pass the 24V threshold: Even considering the volatility of Lithium Polymer batteries? Concerning amperage, I know for a fact that the gun pulls a sustained 2A-35A draw depending on the position of the gears. guess ive never had a problem is the mosfet that had a gate threshold voltage that was higher than what I was driving it with and had a higher Rds than I could work with. Drop-in MOSFETs include several different types form more advanced wired-in solutions to simple plug-and-play units attached in-line with the airsoft gun battery connectors. Use left/right arrows to navigate the slideshow or swipe left/right if using a mobile device. You can learn more about this from our affiliate policy, terms of service, and privacy policy. why would the gate need to be above both the source and the drain voltage (you said 10-12V)? 24V threshold voltage is a red flag saying NOT LOGIC LEVEL. This site does not include all airsoft products or all available product offers. This compensation may impact how and where products appear on this site (including, for example, the order in which they appear). You might think that, youd be completely wrong. Many of the modern MOSFET switches on the market are advanced versions. Users should always check the manufacturer's official website for warranties, user manuals, terms (if any), and product details. First determine if heat is really the culprit. VGS(th) probably targeted for a high current application requiring a higher Vgs to achieve that resistance. At a lower gate voltage the channel is not necessarily formed at all, just a weak-inversion layer. However, the product information listed on highspeedbbs.com is provided without warranty. High-end AEGs can be complicated with low resistance wiring, MOSFET switches, and electronic triggers. isn't it true that as long as the gate voltage is above the source voltage, the mosfet will conduct? Automatic electric airsoft guns (AEGs) are high-performance airsoft guns. For a better experience, please enable JavaScript in your browser before proceeding. FTC Disclosure: Some links may be affiliate links. The gate voltage has to be far enough above the source voltage for that device. if i use a led, the code works fine, turns on then off in "semi" and in "full auto" it blinks on and off, this is what is suppose to happen. it should be safe unless you flinch on the trigger and try to shut off the mosfet with a hundred amps flowing through the motor. Press the space key then arrow keys to make a selection. For most MOSFETs that's 10 to 12V. The airsoft product offers that appear on the website are from respective airsoft industry companies, suppliers, and stores from which High Speed BBs receives compensation. I doubt you'll find the right parts from that, it's only a couple dollars to buy the parts anyways.

We may get paid if you buy something or take an action after clicking one of these. now when i connect the motor on semi it acts like a normal switch? this has a pretty low Rds (< 0.01) very high current (80A). I am interested in part numbers for mosfets, or maybe just fets that at adequate for the small motors i'm using and can be used for braking. http://unconventional-airsoft.com/wp-content/uploads/2009/08/Simple-MOSFET-Setup-2009-06-22.jpg, http://www.chaolimotor.com/EN/product.asp, http://www.infineon.com/dgdl/irlb3034pbf.pdf?fileId=5546d462533600a40153566027b22585, http://www.airsoftguns.ie/2857-thickbox/ad-classic-aeg-standard-motor-long.jpg, airsoft trigger dual mosfet long wires.png, http://m.ebay.com/itm/321057005593?_mwBanner=1, Arduino to Airsoft Gun interface Critique, converted atx supply to power multiple 9.6v 1600mah airsoft guns. MOSFET stands for "metal-oxide-semiconductor-field-effect-transistor". No. I also know that the Battery can safely put out a maximum of 65A for an extended time, though the charge will not last long in that situation. Did you determine yet if it is heat blowing the FET? when i press it in the motor runs intill i lift of the button, when i press the full auto button down it pulse's like it should, what could the cause be? Regardless of the fact that I don't believe your amp numbers, I can optimize the parts. Basic MOSFET switches have the basic setup and electronic load controls found in a MOFSET system.
Would having parallel mosfets split the current/heat? Look at RDS(ON) in the data sheet and see if there is a rating for the voltage level you will be using i.e. If you want to better understand MOSFET switches, we should talk about the different types available. I build little MOSFET systems for Airsoft guns to save the trigger from arching and decrease overall resistance. hey guys so i got the mosfet and wired it all up how i have in the picture. The basic understand of what a MOSFET does is that is handles electrical loads and current in optimized ways by routing electricity through a series of circuits with electronic switches. I would guess that it would still turn on at a lower gate voltage but with a higher Rds. I would guess that it would still turn on at a lower gate voltage but with a higher Rds. Upgrading your airsoft gun AEG with a drop-in MOSFET unit is one of the best gun upgrades you can make. What's everyone's opinion on the Bang Bang rule? Don't forget the TWO required gate resistors, shown below. i have no basic electronic knowledge, so if anyone could help me getting power to the arduino is no issue, i just need help with the wiring. Did your Google search turn up something different? RDS(on) Static Drain-source On Resistance
