Littelfuse, Inc. 12 Amp High Temperature Alternistor TRIAC QJ8012LH5TP

This 12A high temperature Alternistor TRIAC, offered in TO-220AB, TO-220 isolated and TO-263 package, has 150°C maximum junction temperature and 120A ITSM(60Hz).This series enables easier thermal management and higher surge handling capability in AC power control applications such as heater control, motor speed control, lighting controls, and static switching relays. Alternistor TRIAC operates in quadrants I, II, & III and offers high performance in applications requiring high commutation capability. Features: 150C High Junction Temperature with Glass passivated. Surge capability up to 120 A The L-package has an isolation rating of 2500VRMS Solid-state switching eliminates arcing or contact bounce that create voltage transients No contacts to wear out from reaction of switching events Requires only a small gate activation pulse in each half-cycle RoHS Compliant Applications: Excellent for AC switching and phase control applications such as heating, lighting, and motor speed controls. Typical applications are AC solid-state switches, light dimmers, power tools, lawn care equipment, home/brown goods and white goods appliances. Alternistor Triacs (no snubber required) are used in applications with extremely inductive loads requiring highest commutation performance. Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
