3-13. Performance of MOSFETs: Avalanche Capability

As a feature of MOSFET * 1, if it is within a certain energy, drain current ID and below the rated channel temperature Tch, there is performance that does not break even if it exceeds the rated voltage VDSS.
This is called avalanche capability, the allowable energy is called avalanche energy, and the current is called avalanche current.
