Also, will the mosfet turn off when the gate voltage is dropped to 0? It varies according to the device.

I’m not using the mosfets to drive 24 volt robot motors. I just don’t remember if this is how a mosfet works too. So I need the bigger mosfets.

Read the data to see what the series resistance and possible current flow at a particular gate voltage. It works with 5v on the gate and handles a few amps with ease. They datasgeet considerably higher than what it will run with continuously. Any suggestions on a driver that works well with the arduino outputs? JimboZA on Feb 04, At 5 volts it may be 5A while at 10 volts it may be 50A. There are others but make sure they are fully on dataheet 5v on the gate.


I’m using them for a load at v – v at 10amps. Its best to use a gate drive voltage about twice the plateau voltage as this gives roughly symmetrical switching times. I’m sure we’ve been here before with this, but I’ll suggest these drivers again idfp460 you from that other thread we were having discussions.

MarkT Brattain Member Posts: 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. Or does the source voltage have to be 0 as well for the mosfet to turn off? I am thinking of driving the mosfet gate using a push-pull setup with npn pnp BJT transistors. 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, dtaasheet an extreme thermal limit.

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

If anyone could tell me the vital information that I need to know about it, that would be very helpful. I’ve been doing some datasheet, and I think for my purposes I’ll be needing a mosfet driver. 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. The basics that I need to know are the satasheet There’s so many different drivers to choose from. Therefore it is best to have a discharge resistor from gate to Gnd.


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. When you remove the gate voltage, there datasheeh a time taken to discharge the gate capacitor internal.

IRFP Datasheet(PDF) – International Rectifier

Johannesburg hams call me: I bought mine from RS Components. I am planning on purchasing some mosfets for a number of projects I have on the go at the moment. I hope they work with the mosfets I ordered.

And if you have an Internation Rectifier datasheet they lie blatantly about max current anyway. The key parameters you need to look at in a datasheet are: This is important especially when you use PWM as it will get excessively hot without the R.

The maximum specifications are just that, vatasheet that can’t be exceeded. Trying to remember programming C from 25yrs ago.

Here’s the datasheet stats for those transistors: EG, at 2 volts on the gate the current is very low.
