Peak Repetitive Reverse Voltage and others differences

[abdulbadii]

What are, of a diode characteristics, the main differences among:

Peak Repetitive Reverse Voltage

Working Peak Reverse Voltage

DC Blocking Voltage


What importance in distinguishing them while that seems trivial?

Why do you ask?

Repetitive Peak Reverse Voltage (VRRM) The repetitive peak reverse voltage is the maximum instantaneous value of the reverse voltage, including all repetitive transient voltages, but excluding all non- repetitive transient voltages which occur across the device.

Crest (Peak) Working Reverse Voltage (VRWM) The working peak reverse voltage is the maximum instantaneous value of the reverse voltage, excluding all repetitive and non-repetitive transient voltages which occur across the device.

The DC-blocking voltage is the reverse-biased voltage that if exceeded may destroy the diode.

Yeah, still gibberish. This is meaningless without specifying frequency, pulse width and shape, duty cycle, you name it.
I wouldn't be surprised if it's supposed to refer to 60Hz rectification.

Maybe there is a JEDEC standard on it, somewhere...
