JimboZA on Feb 04, Therefore it is best to have a discharge resistor from gate to Gnd. 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’ve been doing some reading, and I think for my purposes I’ll be needing a mosfet driver.

I bought mine from RS Components. I’m using them for a load at v – v at 10amps.

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

At 5 volts it may be 5A while datzsheet 10 volts it may be 50A. EG, at 2 volts on the gate the current is very low. I am planning on purchasing some mosfets for a number of projects I have on the go at the moment. Here is a mosfet I was thinking of buying.


I hope they work with the mosfets I ordered. When you remove the gate voltage, there is a time taken to discharge the gate capacitor internal. There’s so many different drivers to choose from. darasheet

Johannesburg hams call me: Or does the source voltage have to be 0 as well for the mosfet to turn off? 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. It works with 5v on the gate and handles a few amps with ease. MarkT Brattain 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.

The maximum specifications are just that, maximum eatasheet can’t be exceeded. 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. Read the data to see what the series resistance and possible current flow at a particular gate voltage. This is important especially when you use PWM as it will get excessively hot without the R.

Here’s the datasheet stats for those transistors: I want to make sure that I am buying the right mosfets for the job, because these things can be rather expensive. The key parameters you need to look at in a datasheet are: So they work fine with the pwm from the arduino?


With the arduino, you need is a logic level gate mosfet. I am trying to find a 3 or 4 amp transistor that the arduino can turn on. The basics that I need to know are the following: Its best to use a gate drive datasyeet about twice the plateau voltage as this gives roughly symmetrical switching times. There are others but make sure they are fully irfl460 at 5v on the gate. I just don’t remember if this is how a mosfet works too.

It varies according to the device. And if you have an Internation Rectifier datasheet they lie blatantly about max current anyway.

Any suggestions on a driver that works well with the arduino outputs? So I need the bigger mosfets. Trying to remember programming C from 25yrs ago. If anyone could tell me the vital information that I need to know about it, that would be very helpful.
