When the IGBT is turned off, the operating range of the VCE-IC that works safely is called the reverse bias safe operating area (RBSOA: Reverse Bias SafeOperation Area), also known as the switch safe operating area, which refers to the maximum allowable instantaneous voltage during repeated shutdown operation current.

VCES: Collector-Emitter Voltage Of The IGBT The highest allowable off-state collector-emitter voltage in the gate-emitter short circuit condition within the usable junction temperature range. In the manual, VCES is specified at a junction temperature of 25°C, and VCES will decrease as the junction temperature decreases. The relationship between the reduction range and the temperature change can be approximately described by the following formula: .
