T810T-8T

Overview

The T810T-8T is a logic level triac manufactured by STMicroelectronics, rated for an RMS on-state current of 8 A and a repetitive peak off-state voltage of 900 V. It operates within a junction temperature range of -40°C to +150°C and features a maximum gate trigger current of 10 mA, enabling direct microcontroller drive. The device supports a non-repetitive surge current of 63 A and maintains a low holding current of 15 mA. Packaged in the TO-220 Clip Wire Mesabond through-hole format, it complies with ECOPACK2 environmental standards.

Feature Summary

• Logic-level sensitivity allowing direct interface with microcontrollers via low gate current requirements
• Three-quadrant triggering capability for versatile AC switching applications
• ECOPACK2 compliant packaging ensuring environmental safety standards

Applications

• General purpose AC switching circuits
• On/off control functions in AC loads
• Phase angle control applications

Procurement Notes

Verify the specific suffix 'T' against the official datasheet to confirm the through-hole TO-220 Clip Wire Mesabond package variant. Ensure the ordering documentation explicitly references the 900V rating and 8A current capacity to distinguish from other series members. Confirm compliance status matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when high commutation capability and direct logic drive are required without external snubber networks. The 900V rating provides robustness against voltage transients in general AC lines. Verify that the thermal management solution accommodates the TO-220 package dissipation characteristics at the expected operating load currents.

Part Context

This part belongs to the T-Series of medium current triacs designed for industrial and consumer AC power control. It complements other variants like the T810T-8G by offering a through-hole mounting option suitable for traditional PCB layouts or heat sink attachments requiring mechanical robustness.

Replacement Considerations

Direct substitutes include the T810T-8G for surface mount equivalents or the T835T-8I for snubberless applications with similar current ratings. Verify pinout compatibility and thermal resistance values when cross-referencing with alternative manufacturers' logic-level triacs.
