WitrynaThere are several breakdown voltages that are often reported for bipolar junction transistors (BJT). The collector- emitter breakdown voltage, BVcer, is the main limiting factor in the design of a high-voltage driver. This breakdown voltage is a function of the total base resistance, RB, to the ac ground.
