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 T_A=25°C
3. Measured on 8.3ms single half sine-wave or equivalent square wave, duty cycle=4 pulses per minute
maximum.
4. V_F<3.5V for devices of V_BR<200V and V_F<5.0V for devices of V_BR>201V.
