Datasheet
**Teccor[®] brand Thyristors** 4 Amp Sensitive & Standard Triacs RoHS ~~[||~~ ## Lxx04xx & Qxx04xx Series ## **Description** ~~Po~~ 4 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. ## **Features & Benefits** **==> picture [243 x 264] intentionally omitted <==** **----- Start of picture text -----**<br> Agency Approval<br>Lo<br>Agency Agency File Number<br>L Package : E71639<br>9<br>Main Features<br>Lo<br>Symbol Value Unit<br>I 4 A<br>T(RMS)<br>VDRM/VRRM 400 to 1000 V<br>IGT (Q1) 3 to 25 mA<br>—————<br>Schematic Symbol<br>Lo<br>MT2 MT1<br>G<br>**----- End of picture text -----**<br> - RoHS Compliant - contact bounce that create voltage transients - Glass – passivated junctions - No contacts to wear out from reaction of switching events - Voltage capability up to 1000 V - Restricted (or limited) RFI - • Surge capability up to generation, depending on - 55 A activation point of - • Electrically isolated sine wave “L-Package” is UL • Requires only a small gate - Recognized for 2500Vrms activation pulse in each - • Solid-state switching half-cycle eliminates arcing or ## **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. ## **Absolute Maximum Ratings — Sensitive Triacs (4 Quadrants)** ~~Lo~~ |**Absolute Maximum Ratings — Sensitive Triacs (4 Quadrants)**<br>~~Lo~~|**Absolute Maximum Ratings — Sensitive Triacs (4 Quadrants)(4 Quadrants)**<br>~~Lo~~|**Absolute Maximum Ratings — Sensitive Triacs (4 Quadrants)(4 Quadrants)**<br>~~Lo~~|~~Lo~~|~~Lo~~|~~Lo~~| |---|---|---|---|---|---| |Symbol|Parameter|||Value|Unit| |IT(RMS)|RMS on-state current<br>(full sine wave)|Lxx04Ly<br>Lxx04Ry/Lxx04Vy/Lxx04Dy|TC= 90°C<br>TC= 95°C|4|A| |ITSM|Non repetitive surge peak on-state current<br>(full cycle, TJinitial = 25°C)|f = 50 Hz<br>f = 60 Hz|t = 20 ms<br>t = 16.7 ms|33<br>40|A| |I2t|I2t Value for fusing|tp= 8.3 ms||6.6|A2s| |di/dt|Critical rate of rise of on-state current<br>(IG= 50mA with≤0.1μs rise time)|f = 120 Hz|TJ = 110°C|50|A/μs| |IGTM|Peak gate trigger current|tp ≤10 μs|TJ = 110°C|1.2|A| |PG(AV)|Average gate power dissipation||TJ = 110°C|0.3|W| |Tstg|Storage temperature range|||-40 to 150|°C| |TJ|Operating junction temperature range|||-40 to 110|°C| Note: xx = voltage, y = sensitivity © 2016 Littelfuse, Inc.

Good design practice should limit the maximum continuous current through the main terminals to 75% of the device 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. **==> picture [244 x 150] intentionally omitted <==** **----- Start of picture text -----**<br> t P<br>T P<br>Ramp-up<br>T S(max) T L t L<br>Ramp-down<br>Preheat<br>T S(min)<br>t S<br>25<br>time to peak temperature Time<br>Temperature<br>**----- End of picture text -----**<br> ## **Environmental Specifications** **==> picture [246 x 195] intentionally omitted <==** **----- Start of picture text -----**<br> Test Specifications and Conditions<br>MIL-STD-750, M-1040, Cond A Applied<br>AC Blocking<br>Peak AC voltage @ 125°C for 1008 hours<br>MIL-STD-750, M-1051,<br>Temperature Cycling 100 cycles; -40°C to +150°C; 15-min<br>dwell time<br>EIA / JEDEC, JESD22-A101<br>Temperature/<br>1008 hours; 320V - DC: 85°C; 85%<br>Humidity<br>rel humidity<br>MIL-STD-750, M-1031,<br>High Temp Storage<br>1008 hours; 150°C<br>Low-Temp Storage 1008 hours; -40°C<br>Resistance to<br>MIL-STD-750 Method 2031<br>Solder Heat<br>Solderability ANSI/J-STD-002, category 3, Test A<br>Lead Bend MIL-STD-750, M-2036 Cond E<br>**----- End of picture text -----**<br> © 2016 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 410,000+ 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.
