Peak Pulse Power vs. Pulse Duration and Temperature

The approximate calculation method for transient energy was described in the application note of CV01-22. The absorbed energy by TVS diodes is directly associated with their reliability, which indicates the protection level TVS diodes can achieve. Generally, the maximum energy TVS diodes can absorb is a fixed value, which is determined by their junction area, constructions and external environments, such as temperature and package, etc.

On the other hand, the absorbed transient energy can be regarded as the product of dissipated power and time. Therefore, we would try to find the relationship between power and time in this application note, which corresponds to the peak pulse power rating defined as the instantaneous power dissipated by a device for a given pulse condition. The peak pulse power rating can be derived as.......
