It's amazing how small those things are. That's a transistor which can switch four megawatts. A manual switch with the same rating is bigger.
Here's a data sheet for a somewhat larger one.[1] The control signal is only 6 volts at 5 mA. It's incredible that this is physically possible.

- leoedin 2y agoAs an embedded engineer sometimes working on PWM, it's interesting to think that the origin of the gate drive signals is still just some sort of microcontroller timer running at 3.3V and a few mA. I'm sure there's a few layers of level translation and isolation between the micro and the 4 MW power transistor - but it's still indistinguishable at the digital level from a circuit driving a tiny motor on my desk.
