As the title says, thank you

It should be the avalanche test of the power tube

Avalanche energy test is called ESA, and avalanche current test is called IAR

The chip EAS test mentioned by the OP,

For example, for MOS tubes, the quality of EAS characteristics will directly affect the safe operating area and life of the device. For power MOS, EAS characteristics are considered to be an important indicator of device safety.

EAS avalanche testing can eliminate product failures caused by wafer defects and damage caused by the packaging process. It is a conventional testing method and can improve product reliability. Wafer defects and packaging damage can be controlled through some measures during the manufacturing process, thereby reducing the possibility of product failure.
