The trace is on a PCB and very short, with only a pull down resistor on the gate: If your circuit is in an aluminium case this can also be your heatsink. 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. Wawa on Apr 08,mofet As usual, Mr George demands every little bit documented and explained by the books theories to understand whats going on.

Post as a guest Name. More parts and slower switching.

How many do you need? Drive-by” that’s somebody else. Now look at mosffet 3. Use 12V to drive the gate 1k pullup, 1k down divider from 24V and shutoff with an additional NPN inverter to shut off gate.

I cant get this to work. Also I assume both the mosfet and transistor here are both n type? How come this is happening? 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?

Thanks Pancake plus karma I got it to work I think I confused gain drain and source on the mosfet like a newb. 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.

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?

I have a IRF connected to a 5V micro. What you’re attempting should correspond. Yeah that modfet work. This allows the temperature to stabilize, rather than running away. WhatRoughBeast 49k 2 28 I also can make a circuit with just a irf driving some leds on 12v and it also works great.

IRF530, SiHF530 product information

And is “on” when the Arduino is off, and could be “on” during bootup. Notice that at the rated voltage, the drain current will only be uA. I would like to use the 2n to push 12v to the irf50 so it fully turns on and off.

How much does a heatsink cost vs a better FET? AT the least they should rename it like Vgs Cut-Off or something that makes you think about it a different way. That is a great question TonyStewart. And the base drive for Q1 is pretty marginal – I krf530 you’ll get hard saturation.

Therefore it will not conduct fully and act as a resistor.

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. Or is this just not working because I am using the same 12v supply for both mosfet and transistor. You realise the logic mosfet you’re getting does not need a driver transistor.
