What are the applications of diode avalanche energy/reverse surge?

What are the parameters that are often considered when selecting models for diode avalanche energy/reverse surge capability? So, what are the applications of such diode?

1. Products that cannot achieve normal surge impact are defective products

2. Lines with high reverse surge impact from diode, damping/freewheeling... (Devices with high reverse surge capacity should be appropriately considered according to line requirements)

When high reliability is required for circuit devices

4. When the reverse direction needs to resist input abnormal radio wave shock

5. When the circuit operates in a high-temperature environment

Case: When replacing a certain device with GS2M, during high-voltage 3000V reliability testing, there was a large surge impact and the product was abnormal. Product capability is related to structure.
