Sign up or log in Sign up using Google. Go back to your IRF data sheet, and look at the Vgs th rating of 2 to 4 volts. Mosfte 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. It is not specified for 5V.
And that the posted circuit inverts change your code. Even at 5 volts gate drive, you mpsfet not guaranteed to get a whole lot more than this, and this explains your high Rds. Email Required, but never shown.

For 6A and without heatsink, aim for 15 mOhms or lower. Threshold voltage is the Vgs at which is begins to conduct just a little bit, you need way more to have good switching. I would like to use the 2n to push 12v to the irf50 so it fully turns on and off.
I did order some ttl level mosfets from ,osfet they had the lowest price by far even accounting ebay unless you buy a 10 pack from china and wait. As usual, Mr George demands every little bit documented and explained by the books theories to understand whats going on. 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.

How come this is happening? The easiest way is a logic N-channel mosfet, irrf530 switch the low side of the load. And the base drive for Q1 is pretty marginal – I doubt you’ll get hard saturation.
Wawa on Apr 08, Your problem is insufficient Vgs for the device chosen. 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 mosget too much fuss on your part.
Everything runs on smoke, let the smoke out, it stops running 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? The trace is on a PCB and very short, with only a pull down resistor on the gate: Sign up using Facebook. This deals with “normal” irf5300, rather than worst-case.
IRF530 MOSFET. Datasheet pdf. Equivalent
This allows the temperature to stabilize, rather than running away. Also I assume both the mosfet and transistor here are both n type?
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? While others have adequately answered the question, I thought I’d approach it from another perspective, in order to give you some insight as to how to read data sheets. AT the least they should rename it like Vgs Cut-Off or something that makes you think about it a different way.
How can you choose one to keep cool? I will try to post what I did later when I get time but that is pretty much how I i wired it ifr530 except i left out the 22k resistor.
It just kept the lights on no matter what.
High side switching with a P-channel mosfet is another option, but more complicated. There are plenty of such FETs.
I cant get this to work. Finally, look at figure 4, Rds vs temperature, and notice how it rises. Trying to drive a irf mosfet with a 2n transistor.
IRF530, SiHF530 product information
Hence not the rated RdsOn. My main goal is to power some resistance wire for a heat bender. The trace is on a PCB and very short, with only a pull down resistor on the gate:.
