Surge current - thyristor, Electrical Engineering

Surge Current

It is  the maximum admissible peak value of  a sinusoidal half  cycle of 10 ms duration at a frequency of 50Hz. The  value is specified at a given junction temperature .during   maximum  surge on state current  the junction  temperatures exceeded through  temporarily and forward blocking capability are lost  for a short period. The maximum surge on state  current should  only  occur  occasionally.
