I thought that the whole thing is PWM regulated. Must be above 20kHz though becaus I have never heard an audible tone like with trains and other heavy electric motors...

It's the second number on the package.. which is a power fet and fits the app just fine..

I've seen inverted numbers like this many times on packages. '

You asking that question makes it obvious that you should not even be anywhere near the electronics industry.

I'm pretty sure this is a variant package (TO-126 like) of the Fairchild HUF75344, a low R-on (0.008 ohm) 75A 55V N channel MOSFET. Any similarly low-Ron MOSFET would probably sub OK.

Automotive manufacturers picked up big time on MOSFET's as replacements for relays.

I just looked it up on Digi-Key. It sure looks like it has the right specifications.

Nice try, Archie!

Answer the question!

Yeah, that's it! Thanks Jamie!

Yeah, thanks a lot to everyone!!

I earlier posted a link to Future, where it is a dollar less I think.

No accounting for shipping differences, though. And Digikey used to have a $25 minimum to skip another extra charge. Might still be policy.
