Comment on Resistor/Capacitor broke off, anyone knows if it matters?

I think that’s usually the method in high power applications where heat dissipation is paramount. Each of these diodes is only rated for 210mA of drain current. From a BOM cost perspective, it’d be much cheaper to just buy one 5A FET rather than parallelizing a bunch of 0.21A FETs. That 5A FET would be in a package that could handle whatever heat it generates.

You’re probably right—I searched for ‘20 mosfets in parallel’ or something like that and it came up near the top. But I didn’t read the whole thing.
I guess there’s got to be some reason for using so many though?
