Description

This 8 A High Temperature Alternistor Triac solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays. Sensitive type components guarantee gate control in Quadrants I & IV needed for digital control circuitry. Alternistortype components only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability.
