Operation in this mode is accomplished by connecting
Pin 7 to Pin 12 (thus overriding the action of the
zero–crossing detector). When Pin 13 is positive with
respect to Pin 9, current to the thyristor is continuous.

NOTES: 1. Care must be taken, especially when using an external power supply, that total package dissipation is not exceeded.
2.The values given in the Electrical Characteristics Table at 120 V also apply for operation at input voltages of 24 V, 208/230 V, and 277 V, except for
Pulse Duration test. However , the series resistor (RS) must have the indicated value, shown in T able A for the specified input voltage.
