●High Current Triacs
●16 A RMS
●Glass Passivated Wafer
●400 V to 800 V Off-State Voltage
●125 A Peak Current
●Max IGT of 50 mA (Quadrants 1 - 3)
absolute maximum ratings over operating case temperature (unless otherwise noted)
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 400 mA/°C.
3. This value applies for one 50-Hz full-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.
