This paper describes the investigate results of I2 t capability for IGBT module used for xEV powertrain application. I (esp 2) t experiment and simulation evaluations are done by RC-IGBT or the conventional FWD with bondwires structure. As a result, RC-IGBT(wire) has 80% higher I2 t capability compared with FWD in the case of diode active area comparison. In addition, RC-IGBT( leadframe) and RC-IGBT(bondwires) are also evaluated by experimental and simulational approaches. As a result, RCIGBT( leadframe) has additional 33% increase in I 2 t compared to RC-IGBT(wire). Over all, RC-IGBT (leadframe) is x2.4 higher than FWD (bondwires).
