Irvp460 hams call me: I’m using them for idfp460 load at v – v at 10amps. With the arduino, you need is a logic level gate mosfet. I’ve been doing some reading, and I think for my purposes I’ll be needing a mosfet driver.

Therefore it is best to have a discharge resistor from gate to Gnd. The key parameters you need to look at in a datasheet are: There’s so many different drivers to choose from.

And if you have an Internation Rectifier datasheet they lie blatantly about max current anyway. 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. So they work fine with the pwm from the arduino? Also, will the mosfet turn off when the gate voltage is dropped to 0? The basics that I need to know are the following: Datasueet anyone could tell me the vital information that I need to know about it, that would be very helpful.


MarkT Brattain Member Posts: JimboZA on Feb dafasheet, I’m sure we’ve been here before with this, but I’ll adtasheet these drivers again to you from that other thread we were having discussions. I am planning on purchasing some mosfets for a number of projects I have on the go at the moment. They are considerably higher than what it will run with continuously. Trying to remember programming C from 25yrs ago. At 5 volts it may be 5A while at 10 volts it may be 50A.

EG, at 2 volts on the gate the current is very low.

I hope they work with the mosfets I ordered. Its best to use a gate drive voltage about twice the plateau voltage as this gives roughly symmetrical switching times.

Or does the 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. I bought mine from RS Components. It works with 5v on the gate and handles a few amps with ease. 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.


Datssheet am thinking of driving the mosfet gate using a push-pull setup with npn pnp BJT transistors. Here’s the datasheet stats for those transistors: When you remove the gate voltage, there is a time taken to discharge the gate capacitor internal.


The maximum specifications are just that, maximum that can’t be exceeded. 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 am trying to find a 3 or 4 amp transistor that the arduino can turn on. I’m not using the mosfets to irfpp460 24 volt robot motors.

It varies according to the device. Any suggestions on a driver that works well with the arduino outputs? There are others but make sure they are fully on at 5v on the gate. You may also be interested in the body-diode’s performance and datzsheet Vgs max and the plateau voltage usually only hinted at in graphs.

This is important especially when you use PWM as it will get excessively hot without the R. So I need the bigger mosfets.
