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: .
