●Glass Passivated Wafer
●400 V to 800 V Off-State Voltage
●Max IGT of 1 mA
absolute maximum ratings over operating case temperature (unless otherwise noted)
NOTES: 1. These values apply when the gate-cathode resistance RGK = 1 kΩ.
2. These values apply for continuous dc operation with resistive load. Above 80°C derate linearly to zero at 110°C.
3. This value may be applied continuously under single phase 50 Hz half-sine-wave operation with resistive load. Above 80°C derate
linearly to zero at 110°C.
4. 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.
5. This value applies for a maximum averaging time of 20 ms.
