The HGTG20N60A4D is a MOS gated high voltage switching device combining the best features of MOSFETs and bipolar transistors. This device has the high input impedance of a MOSFET and the low on-state conduction loss of a bipolar transistor. The much lower on-state voltage drop varies only moderately between 25 ‘C and 150 ‘C.  The IGBT used is the development type TA49339. The diode used in anti-parallel is the development type TA49372.
