Transistors are often specified with two collector-emitter max voltages: (Vces) collector-emitter voltage (Vbe=0V) (Vceo) collector-emitter voltage (Ib=0A) Vceo(sus) is the Collector-Emitter Sustaining Voltage and its confusing. It’s basically the the collector-emitter breakdown voltage with the base open circuit, which is the most vulnerable state for a transistor. This diagram from Electrical Ratings and Characteristics of […]
