T810H-6G

Overview

The T810H-6G is an 8 A, 600 V logic level TRIAC from STMicroelectronics' H-Series. It is designed for high-temperature operation with a maximum junction temperature of 150 °C. The device features a gate trigger current (I_GT) lower than 10 mA, enabling direct MCU interfacing. It offers high noise immunity and specified minimal commutation levels valid up to the maximum junction temperature. The component utilizes clip bounding technology and complies with RoHS directives.

Feature Summary

• Logic level sensitivity with low gate trigger current for simplified drive circuits
• High-temperature capability allowing operation up to 150 °C junction temperature
• Enhanced thermal dissipation performance reducing heatsink size requirements
• High noise immunity and stable commutation characteristics at elevated temperatures

Applications

• AC power switching in industrial automation systems
• Control units for home appliances and heating equipment
• Motor control applications requiring high reliability
• Building lighting control systems

Procurement Notes

Verify the specific suffix '6G' against the official datasheet to confirm package type and compliance status. Ensure the ordering part number matches the required voltage rating and current capacity for the target application. Cross-reference the manufacturer's latest documentation for any updates on pinout or thermal characteristics before finalizing the design.

Selection Notes

Select this component when high-temperature stability and logic-level gate drive are required. The 150 °C junction temperature rating allows for reduced heatsinking compared to standard 125 °C devices. Verify that the gate drive circuit can supply less than 10 mA to ensure reliable triggering. Consider the 600 V blocking voltage for standard AC mains applications.

Part Context

The T810H-6G belongs to STMicroelectronics' H-Series TRIACs, which are engineered for heavy-duty AC switching. This series emphasizes high-temperature performance and robustness in electrically noisy environments. The H-Series devices replace electromechanical relays by offering solid-state reliability with sparkless operation and no aging effects.

Replacement Considerations

Check for other H-Series variants with different voltage ratings or current capacities if system requirements change. Verify compatibility with existing gate drive circuits when substituting with other logic-level TRIACs. Ensure the replacement device supports the same 150 °C junction temperature limit for thermal management consistency.
