Littelfuse, Inc. Low Power TRIAC up to 1200V Q4012NH5

12Amp 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.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 120 A L-package is UL Recognized for an isolation voltage of 2.5 kVrms Solid-state switching eliminates arcing or contact bounce that create voltage transients No contacts to wear out from reaction of switching events Restricted (or limited) RFI generation, depending on activation point sine wave Requires only a small gate activation pulse in each half-cycle
