New Transfer Mold type SLIMDIP with RC-IGBT and high precision Short Circuit protection function

A new transfer mold type SLIM package DIPIPM(exp TM) (SLIMDIP) developed for small capacity motor drive system in home appliance applications like air-conditioner, washing machine, refrigerator, fan drive etc. that compact size and high reliability are pursued is presented in this paper. The new SLIMDIP is utilizing thin wafer Reverse Conducting IGBT (RC-IGBT) based on the 7th generation CSTBT(exp TM) technology to integrate Free Wheeling Diode (FWD) and IGBT function into a single chip for reducing power chip counts from twelve to six and achieved a more compact package size 30% smaller than Mitsubishi super-mini series DIPIPM(exp TM) products. The module is manufactured by transfer-mold technology that is capable to provide superior matching of mechanical expansion coefficient especially between copper leadframe and the molding material which is contributed to higher reliability.
