Abstract:
Whether different encapsulations and TIMs for TO-package IGBT influences the lifetime is studied. Based on the TO-247 lifetime model, the influence of TIMs thermal gap filler, ceramic, and PCB on lifetime is studied by several PCTs, furthermore, whether lifetimes of TO-263 and TO-220 conform to the lifetime model is also studied. After normalizing lifetime by FE simulation, the results show that TO-247 and TO-220 have similar lifetimes, but TO-263 has longer lifetimes, furthermore, devices with PCB or gap filler have similar lifetimes, but devices with ceramic have shorter lifetimes due to friction.
