The research on lifetime models of power module has already started in the late 1990s. However for the transfer molded discrete package, there is still a shortage of investigation on their power cycling capability regarding lifetime impacting parameters. In this work, first results of developing a lifetime model for transfer molded discrete power devices are shown. Through a study with original devices and locally opened devices of the same type, the impact of epoxy resin molding compound on power cycling capability was investigated.
