“… SIR800 is still worse than the Infineon”

Doesn’t that depend on which Infineon? The 404 is a better performer than the 800, the best Infineon gives slightly better yields than a 404, depends on the light they’re all in just how much you can actually measure, much less see in real world use. The cells still rule the day…

Following the paper trail (specs) is always much different than actual in hand results.

It matters when you are at 80% FET for example, you got also switching losses that add up to conduction losses
This is what does the fake MOSFET likely die it overheats, or at lest significantly heat up the driver
