absolute maximum ratings over operating case temperature (unless otherwise noted)
NOTES: 1. These values apply for continuous dc operation with resistive load. Above 70 °C derate linearly to zero at 110 °C.
2. This value may be applied continuously under single phase 50 Hz half-sine-wave operation with resistive load. Above 70 °C derate
linearly to zero at 110 °C.
3. This value applies for one 50 Hz half-sine-wave when the device is operating at (or below) the rated value of peak reverse volta ge
and on-state current. Surge may be repeated after the device has returned to original thermal equilibrium.
4. This value applies for a maximum averaging time of 20 ms.
