What is a Power Transistor?Power Transistor definitionThe utility model relates to a bipolar junction transistor that can withstand high voltage and high currentPower Transistor structure composition Three-layer semiconductor Two PN junctionsHow Power Transistor workIn power electronics technology, GTR mainly works in the on-off state. GTR usually operates at positive bias (Ib>0) with large current conduction; Reverse bias (Ib<0) is in the cutoff state. Therefore, a sufficiently large puls
