SpletDepending on the device’s characteristics, during the short-circuit, the collector current can be kept at or below a certain level, however the IGBT will still continue to be subjected to … SpletHowever, IGBTs have short-circuit withstand times in the order of microseconds. The short-circuit withstand time of an IGBT is related to its transconductance or gain and the thermal capacity of the IGBT die. Higher gain leads to higher short-circuit current levels within the IGBT whereas lower gain result in lower short-circuit levels.
