# Clarification on Diode Recovery Times and Conduction State

I have a diode in my circuit with reverse voltage of 100 V and forward voltage of 2 V.

It experiences a reverse voltage of 100 V and immediately the voltage changes to 10 V in forward direction so it becomes conductive. What i am curious to know is how much time does it take for diode to become conductive?

I know there are two parameters "reverse recovery time" and "forward recovery time" . But are they related to this matter ?

My understanding is that recovery time is the time for the internal voltage of diode be made both in forward and reverse direction. So when voltage changes from -100 V to +10 V it takes recovery time for diode to change its internal voltage from 100 V to its breakdown voltage (-2 V). Based on this view, the diode should get in its full conductive state, even in the recovery time since the internal 100 V is in direction of current and does not block it. Is my understanding correct?

• Please link the data sheet of the diode and please don't operate it at a reverse voltage equal to its absolute maximum rating. Dec 2, 2023 at 12:30
• What current, and dI/dt? What is the surrounding circuit? How fast is "immediately" really? Please show the waveforms. Dec 2, 2023 at 13:42
