It varies according to the device. Also, will the mosfet turn off when the gate voltage is dropped to 0? EG, at 2 volts on the gate the current is very low. I am trying to find a 3 or 4 amp transistor that the arduino can turn on. There’s so many different drivers to choose from.

I hope they work with the mosfets I ordered. I’m using them for a load at v – v at 10amps. Or does the source voltage have to be 0 as well for the mosfet to turn off? The maximum specifications are just that, maximum that can’t be exceeded.

So they work fine with the pwm from the arduino? You may also be interested in the body-diode’s performance and the Vgs max and the plateau voltage usually only hinted at in graphs. MarkT Brattain Member Posts: Johannesburg hams call me: And if you have irfp60 Internation Rectifier datasheet datashedt lie blatantly about max current anyway. I want to make sure that I am buying the right mosfets for the job, because these things can be rather expensive.


JimboZA on Feb 04, It works with 5v on the gate and handles a few amps with ease. Read the data to see what the series resistance and possible current flow at a particular gate voltage. I’m not using the mosfets to drive 24 volt robot motors.

I just don’t remember if irgp460 is how a mosfet works too. I am planning on purchasing some mosfets for a number of projects I have on the go at the moment.

When you remove the gate voltage, there is ddatasheet time taken to discharge the gate capacitor internal. I bought mine from RS Components. At 5 volts it may be 5A while at 10 volts it may be 50A. I’m sure we’ve been here before with this, but I’ll suggest these drivers again to you from that other thread we were having discussions.

Its best to use a gate drive voltage about twice the plateau voltage as this gives roughly symmetrical switching times. This is important especially when you use PWM as it will get excessively hot without the R.

dztasheet Any suggestions on a driver that works well with the arduino outputs? I’ve been doing some reading, and I think for my purposes I’ll be needing a mosfet driver. So I need the bigger mosfets.


I want to make sure that I am reading and understanding the datasheets, and was hoping some of you people could clarify things for me. Here is a mosfet I was thinking of buying. Therefore it is best to have a discharge resistor from gate to Gnd.

I am thinking of driving the mosfet gate using a push-pull setup with npn pnp BJT transistors. They are considerably higher than what it will run with irrp460.

Trying to remember programming C from 25yrs ago. Here’s the datasheet stats for those transistors: There are others but make sure they are fully on at 5v on the gate. The key parameters you need to look at in a datasheet are: If anyone could tell me the vital information that I need to know about it, that would be very helpful.


With the arduino, you need is a logic level gate mosfet. You don’t need to look at the max current because if you do your sums right with Rds irffp460 you’ll never be anywhere near this, its an extreme thermal limit. The basics that I need to know are the following:
