So they work fine with the pwm from the arduino? There are others but make sure they are fully on at 5v on the gate. I just don’t remember if this is how a mosfet works too. There’s so many different drivers to choose from.

So I need the bigger mosfets. The key parameters you need to look at in a datasheet are: Here is a mosfet I was thinking of buying. MarkT Datsaheet Member Posts: 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 thinking of driving the mosfet gate using a push-pull setup with npn pnp BJT transistors. It varies according to the device. Read the data to see what the series resistance and possible current flow idfp460 a particular gate voltage.


This is important especially when you use PWM as it will get excessively hot without the R. Trying to remember programming C from 25yrs ago.

The maximum specifications are just that, maximum that can’t be exceeded. I’m using them for a load at v – v at 10amps. I bought mine from RS Components. I’m not using the mosfets to drive 24 volt robot motors. I am trying to find a 3 or 4 amp transistor that the arduino can turn on.

Johannesburg hams call me: If anyone could tell me the vital information datqsheet I need to know about it, that would be very helpful. With the arduino, you need is a logic level gate mosfet. When you irf;460 the gate voltage, there is a time taken to discharge the gate capacitor internal.

Here’s irfp4600 datasheet stats for those transistors: I am planning on purchasing some mosfets for a number of projects I have on the go at the moment.

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

Therefore it is best to have a discharge resistor from gate to Gnd. And if you have an Internation Rectifier datasheet they lie blatantly about max current anyway. JimboZA on Feb 04, EG, at 2 volts on the gate the irfp4600 is very low. The basics that I need to know are the following: 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.

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 want to make jrfp460 that I am buying the right mosfets for the job, because these things can be rather expensive. Any dafasheet on a driver that works well with the arduino outputs?

Or does the source voltage have to be 0 as well for the mosfet to turn off? I hope they work with the mosfets I ordered.

IRFP460 Datasheet

I’ve been doing some reading, and I think for my purposes I’ll be needing a mosfet driver. Its best to use a gate drive voltage about twice the plateau voltage as this gives roughly symmetrical switching times. Also, will the mosfet turn off when the gate voltage is datassheet to 0?

At 5 volts it may be 5A while idfp460 10 volts it may be 50A. They are considerably higher than what it will run with continuously. 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.
