If you can\'t find a MOSFET big enough...

And you spent too much time watching it

Reminds me of an article in Popular Electronics half a century
ago. It announced a new 1000-watt (or was it 10kW?) transistor
with a photo showing a TO-3 style case alongside a wrench that
looked tiny by comparison. Probably the April issue.

That\'s crazy, but the guy probably enjoyed it. The FR4 adds a huge
thermal resistance. And those dinky leads and traces won\'t be happy at
600 amps.

Just buy one of these:

1000 amps peak, 1000 watts, 75 volts.

or put a few smaller fets around a heat sink, to spread out the hot
spots.

Someone finally found a use for a 555.
