Lxx04xx & Qxx04xx Series Thyristors 4 Amp Sensitive & Standard Triacs RoHS Description The Lxx04xx and Qxx04xx are 4 Amp bidirectional solid state switch series. They are 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 as needed for digital control circuitry. Standard type devices normally operate in Quadrants I & III.

Lxx04xx & Qxx04xx Series Thyristors 4 Amp Sensitive & Standard Triacs RoHS Description The Lxx04xx and Qxx04xx are 4 Amp bidirectional solid state switch series. They are 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 as needed for digital control circuitry. Standard type devices normally operate in Quadrants I & III triggered from AC line. Agency Approval Agency Agency File Number E71639 Notes: - L Package only. - 400V and 600V for Sensitive Triac (L Device Type) - 400V, 600V, 800V, or 1000V for Standard Triac (Q Device Type) Main Features Symbol IT(RMS) VDRM/ VRRM IGT (Q1) Value 4 400, 600, 800 or 1000 3 to 25 Schematic Symbol Unit A V mA MT2 MT1 G Features & Benefits • RoHS-compliant • Glass – passivated junctions • Voltage capability up to 1000 V • Surge capability up to 55 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 • Restricted (or limited) RFI generation, depending on activation point of sine wave • Requires only a short gate activation pulse in each half-cycle Applications Typical applications are AC solid-state switches, power tools, home/brown goods and white goods appliances. Sensitive gate Triacs can be directly driven by microprocessor or popular opto-couplers/isolators. Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage.
