Ultra compact, low thermal impedance and high reliability module structure with SiC Schottky Barrier Diodes

An advanced module structure for taking advantage of superior characteristics of Silicon Carbide (SiC) device was researched and developed. This structure can realize about four times of power rating density and one half of thermal impedance compared to that of conventional structure. Also, this structure achieved to have higher reliability by applying epoxy molding structure and copper pin connection to conduct current to/from power chips instead of aluminum bonding wire.
