>TO-252 is worse than TO-251
I'm unclear on the difference but at a glance it appears TO-251 would be bigger? I want it as small as possible since I have major space constraints to work within.

My 6 braided solder wick wires will act as the ground plane to wick away heat. Chatgpt said this will be enough to prevent overheating at full throttle indefinitely.

>just buy giant heatsinks that won't fit in your robot and would render all of your CAD work useless
bad idea
heatshrink

>TO-251 is easier to attach copper braid to
what makes that form factor easier to attach copper braid to?

>just use Pchannel

The big downsides of P-channel MOSFETs

Higher R_DS(on)

Same size + price as an N-channel = 2–4× higher on-resistance.

That means more heat, voltage drop, and power loss.

More expensive per performance level.

For high current (motor drive), P-channels cost more and still perform worse.

Less common in low-voltage, high-power designs.

Everyone prefers N-channel efficiency

Why you’re right to stick with N-channel

For your humanoid’s arm controller:

You want tight efficiency (less wasted heat in a small enclosure).

You’re already working with BLDC topology (half-bridges and full-bridges).

Every serious motor controller uses N-channels top and bottom for exactly this reason.
