An analytical model used for analyzing the fast turnoff transient char
acteristics of the complementary insulated-gate bipolar transistor (CI
GBT) [1] is proposed, accounting for the transient charge-sharing effe
ct and the back-injection effect. The normalized turnoff transient cur
rent of the CIGBT is obtained, which is in agreement with the enhanced
SPICE3 simulated results and the experiment. The relationships of the
turnoff time To with the device parameters are given. The modeling me
thodology is also applicable to the mixed LIGBT/LDMOS.
