Datasheet
**Thyristors** 40 Amp Alternistor (High Commutation) and Standard Triacs ## ~~Qxx40xx Series~~ ## ~~[_|5A\~~ ~~**RoHS**~~ ## **Description** The 40 Amp bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed, temperature modulation controls, lighting controls, and static switching relays. Alternistor type components only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability. Standard type devices operate in quadrants I,II,III & IV. **==> picture [504 x 61] intentionally omitted <==** **----- Start of picture text -----**<br> Agency Approval Features & Benefits<br>eee<br>• RoHS Compliant • Surge capability up to<br>Agency Agency File Number<br>400A<br>• Glass – passivated<br>E71639*<br>oc junctions • Electrically isolated<br>**----- End of picture text -----**<br> - Electrically isolated K & J -Packages are UL * - K and J Packages • Voltage capability up to Recognized for 2500Vrms 1000V |**Main Features**<br>**Applications**<br>~~«ee~~|**Main Features**<br>**Applications**<br>~~«ee~~|**Main Features**<br>**Applications**<br>~~«ee~~|**Main Features**<br>**Applications**<br>~~«ee~~| |---|---|---|---| |**Symbol**<br>IT(RMS)<br>VDRM/VRRM|**Value**<br>40<br>400 to 1000|**Unit**<br>A<br>V|Excellent for AC switching and phase control applications<br>such as heating, lighting, and motor speed controls.<br>Typical applications are AC solid-state switches, industrial<br>power tools, exercise equipment, white goods and| |IGT (Q1)|35 to 100|mA|commercial appliances.| **Schematic Symbol** ~~[Po~~ **==> picture [44 x 89] intentionally omitted <==** **----- Start of picture text -----**<br> MT2<br>G<br>MT1<br>**----- End of picture text -----**<br> Alternistor Triacs (no snubber required) are used in applications with extremely inductive loads requiring highest commutation performance.

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. © 2020 Littelfuse, Inc. Specifications are subject to change without notice.

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.
