Littelfuse, Inc. Low Power TRIAC up to 1200V QJ4004V3TP

This 4 A High Temperature 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 devices guarantee gate control in Quadrants I & IV needed for digital control circuitry. Standard type devices normally operate in Quadrants I & III triggered from AC line. 150°C maximum junction temperature Voltage capability up to 600 V Surge capability up to 48A 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 of sine wave Requires only a short gate activation pulse in each half-cycle Halogen free and RoHS compliant
