I am studying the STMicroelectronic BUL216 NPN power transistor. Electrical specification like VCES is given by the Specification Sheet BUL216 Datasheet. Also, the VCEO spec. Both spec has to do with how much high voltage the transistor can withstand before breakdown. Specifications are marked as follow:
- Symbol - Parameter - Value - Unit
- VCES - Collector-Emitter Voltage (VBE = 0) 1600 Volts
- VCEO - Collector-Emitter Voltage (IB = 0) 800 Volts
Technically speaking, what exactly is the difference between VCEO and VCES ?
And what are the exact definitions ?
I also found on the WEB an old Fairchild 1973 Data Book which states that VCES would stand for "Collector to Emitter Saturation Voltage", typically 0.2volt.
Obviously, these two specifications are totally different.
Can anyone clarify those information ? Appreciate your help :)
