T410H-6T

Overview

The STMicroelectronics T410H-6T is a four-quadrant logic-level sensitive triac designed for high-temperature operation up to 150°C without derating. It features a 4 A RMS on-state current and a 600 V repetitive peak off-state voltage. The device utilizes Snubberless technology, ensuring reliable commutation of inductive loads with minimal external circuitry. Key electrical parameters include a maximum non-repetitive surge current of 31 A, a holding current of 15 mA, and a gate trigger current of 10 mA. It operates within a junction temperature range of -40°C to +150°C and is housed in an IPAK through-hole package.

Feature Summary

• Logic-level sensitivity allows direct switching from low-power control circuits with a 10 mA gate trigger current.
• Snubberless design enables reliable commutation of inductive loads without requiring external RC snubber networks.
• High thermal capability supports continuous operation at junction temperatures up to 150°C.

Applications

• Universal motor speed control in household appliances
• Solid-state relay (SSR) implementations
• AC power regulation for heating elements

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm pinout compatibility and packaging type. Ensure that the procurement source provides valid traceability documentation. Confirm that the component meets RoHS compliance requirements as specified in the latest product release notes before finalizing orders.

Selection Notes

Select this component when applications require logic-level gate drive integration to reduce system complexity. The 150°C rating makes it suitable for environments where standard triacs would require significant derating. Verify that the 4 A RMS current capacity aligns with the load requirements, considering potential derating factors if ambient temperatures exceed typical operating ranges.

Part Context

The T410H-6T belongs to the Txx10H series of high-temperature triacs from STMicroelectronics. This series is engineered to replace electromechanical solutions by offering compact size and lower cost through reduced heatsink requirements. It shares the Snubberless architecture with other members of the T410 family but is distinguished by its specific voltage rating and logic-level gate sensitivity optimized for modern control interfaces.

Replacement Considerations

Direct replacements include the T410-600W or T410-6T, provided the pinout and electrical ratings match the application requirements. Verify that substitute components maintain the same 150°C operating temperature limit and logic-level gate sensitivity to ensure circuit compatibility without redesigning the gate driver stage.
