Datasheet
**Thyristors** 12 Amp Alternistor (High Commutation) Triacs ~~**RoHS** =.~~ ## ~~Qxx12xHx Series~~ ## **Description** This 12 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. Standard alternistor triac components operate with in-phase signals in Quadrants I or III and ONLY unipolar negative gate pulses for Quadrant II or III. The alternistor triac will not operate in Quadrant IV. These are used in circuit applications requiring a high dv/dt capability. **==> picture [359 x 57] intentionally omitted <==** **----- Start of picture text -----**<br> requiring a high dv/dt capability.<br>Features & Benefits<br>of Lo<br>**----- End of picture text -----**<br> **==> picture [243 x 19] intentionally omitted <==** **----- Start of picture text -----**<br> Agency Approval<br>Lo<br>**----- End of picture text -----**<br> - RoHS-compliant • No contacts to wear out from reaction of - • Glass – passivated switching events - Glass – passivated junctions **==> picture [168 x 25] intentionally omitted <==** **----- Start of picture text -----**<br> Agency Agency File Number<br>E71639*<br>**----- End of picture text -----**<br> - Restricted (or limited) RFI - • Voltage capability up to generation, depending - 1000 V on activation point sine - • Surge capability up to wave 120 A *** -** L Package Only - Requires only a small - • The L-package has gate activation pulse in an isolation rating of each half-cycle 2500VRMS **==> picture [243 x 80] intentionally omitted <==** **----- Start of picture text -----**<br> Main Features<br>Lo<br>Symbol Value Unit<br>IT(RMS) 12 A<br>VDRM/VRRM 400, 600, 800 or 1000 V<br>IGT (Q1) 10 or 50 mA<br>**----- End of picture text -----**<br> - RMS • Recognized to UL 1557 - • Solid-state switching as an Electrically Isolated eliminates arcing or Semiconductor Device contact bounce that create voltage transients **==> picture [243 x 19] intentionally omitted <==** **----- Start of picture text -----**<br> Schematic Symbol<br>ee,<br>**----- End of picture text -----**<br> ## **Applications** Excellent for AC switching and phase control applications such as heating, lighting, and motor speed controls. **==> picture [150 x 46] intentionally omitted <==** **----- Start of picture text -----**<br> MT2 MT1<br>G<br>**----- End of picture text -----**<br> Typical applications are AC solid-state switches, light dimmers, power tools, lawn care equipment, home/brown goods and white goods appliances.

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.

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.

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.
