25 Amp bi-directional 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.Standard type devices normally operate in Quadrants I & III triggered from AC line. Alternistor type devices only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability. RoHS compliant Glass-passivated junctions Voltage capability up to 1 kV Surge capability up to 250 A
