Its best to use a gate drive voltage about twice the plateau voltage as this gives roughly symmetrical switching times. I just don’t remember if this is how a mosfet irf4p60 too. It varies according to the device. I am planning on purchasing some mosfets for a number of projects I have on the go at the moment. This is important especially when you use PWM as it will get excessively hot without the R.

The maximum specifications are just that, maximum that can’t be exceeded. If anyone could tell me the vital information that I need to know about it, that would be very helpful. At 5 volts it may be 5A while at 10 volts it may be 50A. 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’ve been doing some reading, and I think for my purposes I’ll be needing a mosfet driver.


There’s so many different drivers to choose from.

So I need the bigger mosfets. Johannesburg hams call me: There are others but make sure they are fully on datqsheet 5v on the gate. MarkT Brattain Member Posts: Any suggestions 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?

So they work fine with the pwm from the arduino? 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.

They are considerably higher than what it will run with continuously. Read the data to see what the series resistance and possible current flow at a particular gate voltage. irf4p60

I bought mine from RS Components. Here’s the datasheet stats for those transistors: I’m not using the mosfets to drive 24 volt robot motors.


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. And if you have an Internation Rectifier datasheet they lie blatantly about max current anyway. When you remove the gate voltage, there is a time taken to discharge the gate capacitor internal. I’m using them for a load at v – v at 10amps.

EG, at 2 volts on the gate the current is very low. With the arduino, you need is a logic level gate catasheet. The basics that I need to know are datawheet following: I hope they work with the mosfets I ordered. The key parameters you need to look at in a datasheet are: It works with 5v on the daatasheet and handles a few amps with ease. 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.

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. Trying to remember programming C from 25yrs ago. I want to make sure that I am buying the right mosfets for the job, because these things can be rather expensive.

Here is a mosfet I was thinking of buying. JimboZA on Feb 04, Also, will the mosfet turn off irfp4660 the gate voltage is dropped to 0?

I am trying to find a 3 or 4 amp transistor that the arduino can turn on.
