It works with 5v on the gate and handles a few amps with ease.


Trying to remember programming C from 25yrs ago. Therefore it is best to have a discharge resistor from gate to Gnd. So I need the bigger mosfets.

I am planning on purchasing some mosfets for a number of projects I have on the go at the moment. Also, will the mosfet turn off when the gate voltage is dropped to 0?

I hope they work with the mosfets I ordered. This is important especially when you use PWM as it will get excessively hot without the R. JimboZA on Feb 04, It varies according to the device.

Here is a mosfet I was thinking of buying.

There’s so many different drivers to choose from. 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. I bought mine from RS Components. You don’t need to look at the max current because if you do your sums right with Rds on you’ll never be anywhere near this, its an extreme thermal limit.


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. I’m not using the mosfets to drive 24 volt robot motors.

So they work fine with the pwm from the arduino? I just don’t remember if this is how a mosfet works too. I want to make sure that I am buying the right mosfets for the job, because these things can be rather expensive. I’ve been doing some reading, and I think for my purposes I’ll be needing a mosfet driver. With the arduino, you need is a logic level gate mosfet.

If anyone could tell me the vital information that I need to know about it, that would be very helpful. Its best to use a gate drive voltage about twice the plateau voltage as this gives roughly symmetrical switching times.

At 5 volts it may be 5A while at 10 volts it may be 50A.

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 datasheeh continuously.


There are others but make sure they are fully on at 5v on the gate. I’m using them for a load at v – v at 10amps. Here’s the datasheet stats for those transistors: MarkT Brattain Member Posts: I am trying to find a 3 or 4 amp transistor that the arduino can turn on.

Any suggestions on a driver that works well with the arduino outputs? EG, at 2 volts on the gate the current is very low.

And if you have an Internation Rectifier datasheet they lie blatantly about max current anyway. Johannesburg hams call me: 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. The basics that I need to know are the following: The key parameters you need to look at in a datasheet are: The maximum specifications are just that, maximum that can’t be exceeded. Or does adtasheet source voltage have to be 0 as well for the mosfet to turn off?

Read the data to see what the series resistance and possible current flow at a particular gate voltage. When you remove the gate voltage, there is a time taken to discharge the gate capacitor internal.
