Test of metal power transistor

Not sure I understood all what he was trying to convey in the video, but we can tell he did not bother checking the datasheet when he bashes the 2n3055 for its beta droop at high-ish current range, 1.5A and greater, as "serious wrong",
while the datasheet indeed predicts the behavior of the device shown on the tracer, a 50% or more decline in beta @ 3A vs @ 0.5A. Maybe he was marketing AP01N by demonstrating its superior performance in retaining current gain at high Ic range?

In China, there are many fake electronic components
Fake BJT, fake MOSFET, fake IGBT, fake IC, fake Cap
Just search for a component, like 2sc5200, and if you don’t identify it carefully, the probability of buying a fake is greater than 90%.
