NOTES: 1. These values apply bidirectionally for any value of resistance between the gate and Main Terminal 1.
2. This value applies for 50-Hz full-sine-wave operation with resistive load. Above 70°C derate linearly to 110°C case temperature at
the rate of 200 mA/°C.
3. This value applies for one 50-Hz full-sine-wave when thedevice is operating at (or below) the rated value of on-state current. Surge
may be repeated after the device has returned to original thermal equilibrium. During the surge, gate control may be lost.
4. This value applies for a maximum averaging time of 20 ms.
