Abstract :
The failure of punch-through (PT) IGBTs to reach forward conduction mode at cryogenic temperatures has already been observed in previous work, but no explanation has been given. In this work detailed experimental data collected for PT IGBTs are presented. The forward conduction drops and switching behavior of the IGBTs are examined over a temperature range from 4.2 to 295 K. The phenomenon under analysis is presented. Connections between the failure of PT-IGBTs and other phenomena are highlighted. Physical behavior at low junction temperatures is analyzed and the failure at cryogenic temperatures is discussed and analyzed.
