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 25oC and 150oC. The IGBT used is the development type TA49170. The diode used in anti-parallel with the IGBT is the development type TA49053.
The IGBT is ideal for many high voltage switching.
