Thyristors 8 Amp Sensitive, Standard & Alternistor (High Commutation) Triacs RoHS Lxx08xx & Qxx08xx & Qxx08xHx Series Description This 8 Amp bidirectional 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 as needed for digital control circuitry. Standard type components normally operate in Quadrants I & III triggered from AC line. Alternistor type components only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability.

Typical applications are AC solid-state switches, light MT2 MT1 dimmers, power tools, home/brown goods and white goods appliances. Alternistor Triacs (no snubber required) are used in G applications with extremely inductive loads requiring highest commutation performance. Additional Information Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage. Datasheet Resources Samples 2020 Littelfuse, Inc.
