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 irp460 this, its an extreme thermal limit. And if you have an Internation Rectifier datasheet they lie blatantly about max current anyway.
There’s so many different drivers to choose from.
With the arduino, you need is a logic level gate mosfet. So I need the bigger mosfets. I just don’t remember if this is how a mosfet works too.
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.

So they work fine with the pwm from the arduino? This is important especially when you use PWM as it will get excessively hot without the R. There are others but make sure they are fully on at 5v on the gate. I want to make sure that I am buying the right mosfets for the job, because these things can be rather expensive. 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’m not using the mosfets to drive 24 volt robot motors.
Any suggestions on a driver that works well with the arduino outputs? JimboZA on Feb 04, 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. At 5 volts it may be 5A while at 10 volts it may be 50A. I’ve been doing some reading, and I think for my purposes I’ll be needing a mosfet driver.
It works with 5v on the gate and handles a few amps with ease. Also, will the mosfet turn off when the gate voltage is dropped to 0? EG, at 2 volts on the gate the current is very low.
Or does the source voltage have to be 0 as well for the mosfet to turn off? Johannesburg hams call me: Therefore it is best to have a discharge resistor from gate to Gnd. I am planning on purchasing some mosfets for a number of projects I dtaasheet on the go at the moment. 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 voltage about twice the plateau voltage as dstasheet gives roughly symmetrical switching times. 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’m using them for a load at v – v at 10amps. Here is a mosfet I was thinking of buying.
When you remove the gate voltage, there is a time taken to discharge the gate capacitor internal. Here’s the datasheet stats for those transistors: MarkT Brattain Member Posts: I bought mine from RS Components. Read the data to see what the series resistance and possible current flow at a particular gate voltage.

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.
It varies according to the device. I hope they work with the mosfets I ordered. The key parameters you need to look at in a datasheet are: The maximum specifications are just that, maximum that can’t be exceeded.
