How can you choose one to keep cool? Finally should I put a heatsink on the back of the mosfet and one on the top because I can or will that draw heat up through the chip and be a no no? Your problem is insufficient Vgs for the device chosen.

Therefore it lrf530 not conduct fully and act as a resistor. I am above the threshold voltage of 4V, so I assume the FET is not in a linear state, and the power dissipation according to Rds on is only 0.

And the base drive for Q1 is mosfrt marginal – I doubt moafet get hard saturation. And that 22k needs to be 1k to lower switching losses.

I would like to use the 2n to push 12v to the irf50 so it fully turns on and off. If you can mount it bare can you mount multiple irf5x0 on the same heatsink bare? Go back to your IRF data sheet, and look at the Vgs th rating of 2 to 4 volts. What you’re attempting should correspond.

How come this is happening? There are plenty of such FETs. High side switching with a P-channel mosfet is another option, but more complicated. I’ve posted this circuit more than once — Go To Reply 14 For The Latest Version It’s not optimized for yeah, you know, well every damn thingso it offends snarky ol’ Mr.

This is in contrast with BJTs bipolar junction transistors whose effective resistance drops with rising temperature, which can lead to runaway thermal failure. I am thinking the problem arises because I am sinking the negative side of the leds through the transistor instead of putting power out of the transistor should I be using a p chanel transistor to feed the mosfet its 12v to turn on?

Drive-by” that’s somebody else. It just kept the lights on no matter what. Yeah that will work.

Hence not the rated RdsOn. My main goal is to power some resistance wire for a heat bender. WhatRoughBeast 49k 2 28 Hi, Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png or pdf?

Sign up using Facebook. When I set the pin to high, the mosfet gets very hot.

Also I assume both the mosfet and transistor here are both n type? Sign up or log in Sign up using Google. Mofset, look at figure 4, Rds vs temperature, and notice how it rises.

And that the posted circuit inverts change your code.

mosfet – IRF getting very hot – Electrical Engineering Stack Exchange

As usual, Mr George demands every little bit documented and explained by the books theories to understand whats going on. That is a great question TonyStewart. Sign up using Email and Password. Just trying to get a circuit working on 12v and leds before I move up to the resistance wire and 48v.

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. This deals with “normal” behavior, rather than worst-case.

If your circuit is in an aluminium case this can also be your heatsink. Email Required, but never shown. I have a IRF connected to a 5V micro. IRF getting very hot Ask Question. You realise the logic mosfet you’re getting does not need a driver transistor.
