Where does the unclamped inductive switching (UIS) test for MOS tubes come from? Are there any test standards?

The test standard should be no

This is not a routine test. There is no test standard or industry test specification. The test simulates the power device under extreme electrical and thermal stress. It is to judge the ability of MOS tube to withstand extreme electrical environment, such as high current and high voltage.

The EAS value of this single pulse indicator is included in the MOS tube specification, which reflects the ability of avalanche breakdown and the ability to withstand UIS.

For details, please consult MOS pipe company

Which IEC or IEEE standards are used for testing, or their general test methods, as the test methods used by general electronics companies with existing oscilloscopes, DC power supplies, etc.

It's probably not a trade secret.
