Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. Non-repetitive current pulse and derated above TA=25°C
3. Measured on 8.3ms single half sine-wave or equivalent square wave, duty cycle=4 pulses per minute
maximum.
4. VF<3.5V for devices of VBR<200V and VF<5.0V for devices of VBR>201V.
