T810H-6G-TR

Overview

The T810H-6G-TR is an H-Series triac from STMicroelectronics, rated for 8 A RMS on-state current and 600 V repetitive peak off-state voltage. It features a logic-level gate sensitivity with a maximum gate trigger current of 10 mA, enabling direct interface with low-power drivers. The device supports a maximum junction temperature of 150 °C and operates within a temperature range of -40 °C to +125 °C. Packaged in a DPAK (TO-252) surface-mount format, it includes clip bounding for enhanced mechanical stability.

Feature Summary

• Logic level sensitivity allows direct interfacing with microcontrollers without additional drive circuitry.
• High thermal capability supports operation at junction temperatures up to 150 °C for improved power density.
• Snubberless design provides high commutation performance suitable for inductive loads.

Applications

• Static relays
• Heating regulation systems
• Induction motor starting circuits

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when system design requires a surface-mount TRIAC capable of handling 8 A continuous load with logic-level gate drive. The 600 V rating suits general AC switching applications. Verify that the DPAK package footprint aligns with the PCB layout constraints and that the thermal management strategy accommodates the 150 °C junction temperature limit under expected operating conditions.

Part Context

This part belongs to the ST H-Series triac family, which emphasizes high-temperature operation and logic-level compatibility. The series is engineered to replace electromechanical solutions by offering optimized heatsink sizes and reduced space requirements. The T810H variant specifically targets medium-current AC switching applications requiring robust thermal performance and reliable commutation characteristics.

Replacement Considerations

Direct substitutes include other ST H-Series triacs such as the T810H or T810B, provided the voltage and current ratings match the application requirements. Verify pinout compatibility and package dimensions before substitution to ensure seamless integration into existing designs without modifying the PCB layout.
