IRF530 Power MOSFET

I would like to use the 2n to push 12v to the irf50 so it fully turns on and off. WhatRoughBeast 49k 2 28 Sign up using Facebook. Wawa Shannon Member Posts: Use 12V to drive the gate 1k pullup, 1k down divider from 24V and shutoff with an additional NPN inverter to shut off gate. Itf530 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?

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. This is in contrast with BJTs bipolar junction transistors whose effective resistance drops with rising temperature, which can lead to runaway thermal failure. I have a IRF connected irrf530 a 5V micro. Your problem is insufficient Vgs for the device chosen.

Tony EE rocketscientist 62k 2 21 And that 22k needs to be 1k to lower switching losses. You realise the logic mosfet you’re getting does not need a driver transistor.

There are plenty of such FETs. On shorter lengths of LEDs, it only gets marginally warm.

At 5 volts gate voltage, you can only “expect” 3 to 4 amps of current, and you want 6, so this also should give you warning. Even at 5 volts gate drive, you are not guaranteed to get a whole lot more than this, and this explains your high Rds.

My main goal is to power some resistance wire for a heat bender. This deals with “normal” behavior, rather than worst-case. Drive-by” that’s somebody else. Hello I can make a circuit where the 2n can drive the leds and the arduino can pwm them and it works great. The trace is on a PCB and very short, with only a pull down resistor on the gate: I will try to post what I did later when I get time but that is pretty much how I i wired it anders except i left out the 22k resistor.

As usual, Mr George demands every little bit documented and explained by moscet books theories to understand whats going on. 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. It’s very useful for connecting FETs in parallel, since if one is hogging the current, its resistance will rise and it will draw less current, allowing equal current sharing without too much fuss on your part.

Email Required, but never shown. I cant get this to work. It just kept the lights on no matter what. High side switching with a P-channel mosfet is another option, but more complicated. Finally, look at figure 4, Rds vs temperature, and notice how it rises. Notice that at the rated voltage, the drain current will only be uA. I am thinking the problem arises because I am sinking the negative side of the leds through the transistor instead of putting iff530 out of the transistor should I be using a p chanel transistor to feed the mosfet its 12v to turn on?

That is a great question TonyStewart.

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 allows the temperature to stabilize, rather than running away. Wawa on Apr 08, More parts and slower switching. Also I assume both the mosfet and transistor here are lrf530 n type?
