Datasheet
Thyristor **Datasheet** ## **LJxx08xx & QJxx08xHx & QJxx08xx Series** 8 Amp High Temp Sensitive,Standard & Alternistor(High Communication)Triacs ## **RoHS** HF L_] ## **Description** This 8 A High Temperature Alternistor Triac 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. **Alternistor** type components only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability. Standard type devices normally operate in Quadrants I & III triggered from AC line ## **Additional Information** ## **Features & Benefits** - 150°C maximum junction ■ Restricted (or limited) RFI temperature generation, depending on - ■ Voltage capability up activation point of to 800V sine wave **==> picture [198 x 7] intentionally omitted <==** **----- Start of picture text -----**<br> Resources Accessories Samples<br>**----- End of picture text -----**<br> ## **Agency Approvals and Environmental** |**Environmental Approvals**|**Environmental Approvals**|**Environmental Approvals**| |---|---|---| ||**RoHS**|| **Note:** UL recognition agency file number E71639 (L package only) ## **Main Features** |**Symbol**|**Value**|**Unit**| |---|---|---| |IT(RMS)|8|A| |VDRM/VRRM|400 or 600 or 800|V| |IGT (Q1)|10 to 50|mA| - Surge capability up ■ Requires only a short gate to 100A at 60Hz half cycle activation pulse in each halfcycle - Solid-state switching eliminates arcing or contact ■ Halogen free and RoHS bounce that create voltage compliant transients - No contacts to wear out from reaction of switching events ## **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 high inductive loads requiring the highest commutation performance. **Schematic Symbol** **==> picture [156 x 48] intentionally omitted <==** **----- Start of picture text -----**<br> MT2 MT1<br>G<br>**----- End of picture text -----**<br> © 2021 Littelfuse, Inc. **1** Specifications are subject to change without notice. ~~(2. 0...~~ © 2021 Littelfuse, Inc.

Good design practice should limit the maximum continuous current through the main terminals to 75% of the component rating. Other ways to ensure long life for a power discrete semiconductor are proper heat sinking and selection of voltage ratings for worst case conditions. Overheating, overvoltage (including dv/dt), and surge currents are the main killers of semiconductors. Correct mounting, soldering, and forming of the leads also help protect against component damage. ## **Environmental Specifications** |**Test**|**Specifications and Conditions**| |---|---| |**AC Blocking (VDRM)**|MIL-STD-750, M-1040, Cond A Applied<br>Peak AC voltage @ 150°C for 1008 hours| |**Temperature Cycling**|Peak AC voltage @ 150<br>MIL-STD-750, M-1051, 1000 cycles;<br>-55°C to +150°C; 15-min dwell-time| |**Temperature/Humidity**|EIA / JEDEC, JESD22-A101 1008 hours;<br>320V-DC: 85°C; 85% rel humidity| |**High Temp Storage**|C; 85% rel humidity<br>MIL-STD-750, M-1031, 1008 hours;<br>150°C| |**Low-Temp Storage**|1008 hours;-40°C| |**Resistance to Solder Heat**|MIL-STD-750 Method 2031| |**Solderability**|ANSI/J-STD-002,category3,Test A| |**Lead Bend**|MIL-STD-750,M-2036 Cond E| © 2021 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.
