Thyristors 8 Amp Sensitive, Standard & Alternistor (High Commutation) Triacs Lxx08xx & Qxx08xx & Qxx08xHx Series RoHS 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. Agency Approval Features & Benefits • RoHS compliant • No contacts to wear out Agency Agency File Number from reaction of switching • Glass – passivated E71639* events junctions * - L Package Only • Voltage capability up • Restricted (or limited) RFI generation, depending on to 1000 V Main Features activation point of • Surge capability up sine wave to 100 A Symbol Value Unit • Requires a short gate • The L-package has activation pulse during I 8 A T(RMS) an isolation rating of each half-cycle V /V 400, 600, 800 or 1000 V 2500V DRM RRM RMS I 5 to 50 mA • Solid-state switching GT (Q1) eliminates arcing or contact bounce that create voltage transients Schematic Symbol Applications Excellent for AC switching and phase control applications such as heating, lighting, and motor speed controls. MT2 MT1 Typical applications are AC solid-state switches, light dimmers, power tools, home/brown goods and white goods appliances. G Alternistor Triacs (no snubber required) are used in 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 © 2018 Littelfuse, Inc.
