Abstract :
This thesis presents typical results of a long-term life-test on P-N-P-N power thyristors with diffused alloyed junctions. Devices are tested under thermal cycle operating conditions for 6 years (50 000 hours) real time. Degradation and catastrophic failures are discussed. Electrical phenomena are correlated with failure rates.
