Anyone who's working on any unit and using any pmc chinese transistors, here is some die measurements.

Anyone who's working on any unit and using any pmc marked chinese transistors, here is some die measurements. It's a 2SC3519
I accidentally killed this one with arround only 20volt dc
Looking like 3.5mm die size i dont know if its good or not.
I used some pliers to open up this transistor.
Edit1: I use this transistor in my amplifier (Pioneer sa7800) it holds up with a TO220 70-90watt transistor. I plan to replace it with something genuine.

same, i asked the guy in the shop that where is it from since i thought that those pmc transistors are actually decent, but its not, we have MG-eletronics there where it was, luckily its out of stock and its gone for good.
