What is the PIV rating of transistor?

The PIV (Peak Inverse Voltage) rating of a transistor, particularly in the context of bipolar junction transistors (BJTs) and diodes, refers to the maximum reverse voltage that the device can withstand without breaking down. For BJTs, the PIV is typically related to the collector-emitter voltage (V_CE) in reverse bias conditions. Exceeding the PIV rating can lead to failure or damage of the transistor, so it is crucial to operate within specified limits to ensure reliability and longevity.
