Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the selected component meets the required voltage and current ratings for the target application. Cross-reference the RoHS and REACH compliance status with the latest regulatory documentation provided by STMicroelectronics before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring logic-level triggering for AC power control. The 800V rating provides sufficient margin for standard mains applications. Consider the IPAK package for through-hole mounting requirements. Evaluate the thermal management needs based on the 125°C maximum junction temperature limit and the specific RMS current demands of the load.

Part Context

This part belongs to the T410 series of logic level triacs from STMicroelectronics. The series is characterized by Snubberless technology, which simplifies circuit design by eliminating the need for snubber networks. These devices are engineered for high reliability in switching applications involving inductive loads, offering robust performance in consumer and industrial electronics.

Replacement Considerations

Consult the official STMicroelectronics replacement guide for verified equivalent parts. Ensure any substitute maintains the same voltage rating, current handling capability, and package type. Verify that alternative components support logic-level gate triggering if direct MCU interfacing is required.
