2014 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 12/14/14 Teccor brand Thyristors 8 Amp Sensitive, Standard & Alternistor (High Commutation) Triacs Lxx08xx & Qxx08xx & Qxx08xHx Series Main Features Description 8 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. 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. Alternistor and are used in circuits requiring high dv/dt capability. Symbol Value Unit I T(RMS) 8 A V DRM /V RRM 400 to 1000 V I GT (Q1) 5 to 50 mA Features & Benefits junctions to 1000 V to 100 A recognized for 2500Vrms eliminates arcing or contact bounce that create voltage transients from reaction of switching events generation, depending on activation point of sine wave activation pulse in each half-cycle 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, 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.
