Or is this just not working mosfey I am using the same 12v supply for both mosfet and transistor. More parts and slower switching. Wawa Shannon Member Posts: If you can mount it bare can you mount multiple irf5x0 on the same heatsink bare?

How many do you need? The trace is on a PCB and very short, with only a pull down resistor on the gate: Can post a schematic if you want. Well I looked at the data sheet and basically it doesn’t say anything about the tab or hell kosfet didnt know to call it a tab because it doesn’t label it as that etc etc. I have a IRF connected to a 5V micro.


How come this is happening?

The easiest way is a logic N-channel mosfet, and switch the low side of the load. At 5 volts gate mosfer, you can only “expect” 3 to 4 amps of current, and you want 6, so this also should give you warning. Your problem is insufficient Vgs for the device chosen.

Post as a guest Name. Hence not the rated RdsOn. I would like to use the 2n to push 12v to the irf50 so it fully turns on and off. AT the least they should rename it like Vgs Cut-Off or something that makes you think about it a mosfe way.

Trying to drive a irf mosfet with a 2n transistor. And the base drive for Q1 is pretty marginal – I doubt you’ll get hard saturation. It just kept the lights on no matter what.

irf503 Thanks Pancake plus karma I got it to work I irrf530 I confused gain drain and source on the mosfet like a newb. Hello I can make a circuit where the 2n can drive the leds and the arduino can pwm them and it works great. Everything runs on smoke, let the smoke out, it stops running And that the posted circuit inverts change your code.

IRF530, SiHF530 product information

If you can tell me what page and what piece of info says it on the datasheet maybe i can learn where to look next time. Go back to your IRF data sheet, and look at the Vgs th rating of 2 to 4 volts. High side switching with a P-channel mosfet is another option, but more complicated. As usual, Mr George demands every little bit documented and explained by the books theories to understand whats going on.


This allows the temperature mosdet stabilize, rather than running away.


I did order some ttl level mosfets from sparkfun they had the lowest price by far even accounting ebay unless you buy a 10 pack from china and wait. This is in contrast with BJTs bipolar junction transistors whose effective resistance drops with rising temperature, which can lead to runaway thermal failure.

WhatRoughBeast 49k 2 28 Now look at figure 3. Threshold voltage is the Vgs at which is begins to conduct just a little bit, you need way more to have good switching.

And irf5330 “on” when the Arduino is off, and could be “on” during bootup. Drive-by” that’s somebody else. I cant get this to work.
