**Thyristors** 8 Amp Sensitive, Standard & Alternistor (High Commutation) Triacs **RoHS** ~~\\~~ ## Lxx08xx & Qxx08xx & Qxx08xHx Seri ~~es~~ ## **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. **==> picture [258 x 50] intentionally omitted <==** **----- Start of picture text -----**<br> Agency Approval<br>es )§=«<br>Agency Agency File Number<br>E71639*<br>**----- End of picture text -----**<br> * - L Package Only **==> picture [244 x 74] intentionally omitted <==** **----- Start of picture text -----**<br> Main Features<br>OOO<br>Symbol Value Unit<br>IT(RMS) 8 A<br>VDRM/VRRM 400, 600, 800 or 1000 V<br>IGT (Q1) 5 to 50 mA<br>**----- End of picture text -----**<br> ## **Features & Benefits** - RoHS-compliant - No contacts to wear out from reaction of switching events - Glass – passivated junctions - Restricted (or limited) RFI generation, depending on activation point of sine wave - Voltage capability up to 1000 V - Surge capability up to 100 A - Requires a short gate - • The L-package has activation pulse during an isolation rating of each half-cycle 2500VRMS - Solid-state switching eliminates arcing or contact bounce that create voltage transients **==> picture [505 x 182] intentionally omitted <==** **----- Start of picture text -----**<br> Schematic Symbol Applications<br>ee<br>Excellent for AC switching and phase control applications<br>such as heating, lighting, and motor speed controls.<br>(4<br>MT2 MT1 Typical applications are AC solid-state switches, light<br>dimmers, power tools, home/brown goods and white<br>goods appliances.<br>FF.<br>G Alternistor Triacs (no snubber required) are used in<br>applications with extremely inductive loads requiring<br>highest commutation performance.<br>Additional Information<br>Internally constructed isolated packages are offered for<br>3 ease of heat sinking with highest isolation voltage.<br>Datasheet Resources Samples<br>**----- End of picture text -----**<br> © 2020 Littelfuse, Inc.

Updated at June 8, 2026
Founded in 1927 and headquartered in Chicago, Illinois, Littelfuse is a premier global manufacturer of circuit protection, power control, and sensing technologies. Widely recognized for pioneering the first small, fast-acting protective fuse, the company has grown into an industry leader whose highly reliable components are essential to modern industrial, transportation, and consumer electronics applications worldwide. At the core of the Littelfuse portfolio is an expansive and industry-leading range of circuit protection solutions. This encompasses a massive selection of traditional fuses, fuse holders, and resettable PTC thermistor fuses designed to safely interrupt overcurrent conditions. To defend against electrical overstress, Littelfuse also provides advanced transient voltage suppression (TVS) technologies, including thousands of specialized TVS diodes, TVS varistors, and gas discharge tubes (GDTs) that ensure robust defense against voltage spikes and environmental hazards. Beyond its foundational protection components, Littelfuse manufactures a diverse array of discrete semiconductors, sensors, and switching devices. Engineers rely on their high-performance thyristors, including TRIACs and SCRs, alongside power-efficient Schottky diodes and MOSFETs for demanding power control applications. Complemented by precision proximity sensors and highly reliable reed and solid-state relays, Littelfuse delivers the critical building blocks required for secure, efficient, and complete system design.
About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 540,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
