T810-600B

Overview

The T810-600B is a logic-sensitive gate Triac manufactured by STMicroelectronics, designed for AC power switching applications. It features a maximum on-state current of 8 A and a repetitive peak off-state voltage rating of 600 V. The device operates within a junction temperature range of -40°C to 125°C and is housed in a surface-mount DPAK (TO-252-3) package. Key electrical parameters include a maximum non-repetitive peak on-state current of 80 A or 84 A depending on the waveform, a maximum gate trigger voltage of 1.3 V, and a maximum gate trigger current of 10 mA. The holding current is rated at a maximum of 15 mA.

Feature Summary

• Logic-sensitive gate architecture enables direct interfacing with microcontroller outputs without requiring high drive currents.
• Snubberless design provides immunity to voltage transients, simplifying circuit topology and reducing component count.
• Surface-mount DPAK packaging facilitates automated assembly and compact board layout for consumer electronics.

Applications

• General-purpose AC switching in household appliances
• Phase-angle control circuits for lighting dimmers
• Motor speed control in small home appliances

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity. Check for any updated datasheet revisions that may affect mechanical dimensions or thermal characteristics before finalizing the bill of materials.

Selection Notes

Select this component for applications requiring moderate current handling up to 8 A RMS with low gate drive requirements. The 600 V blocking voltage suits single-phase AC mains applications. Consider the thermal resistance of the DPAK package and ensure adequate PCB copper area for heat dissipation to maintain junction temperature within the specified 125°C limit under continuous load conditions.

Part Context

This part belongs to the T8xx series of Triacs from STMicroelectronics, which are optimized for cost-sensitive consumer electronics. The series offers a balance of performance and reliability for AC power control tasks. The T810 variant specifically targets the 8 A current class, providing a robust solution for general-purpose switching where space constraints favor surface-mount technology over through-hole alternatives.

Replacement Considerations

Direct pin-compatible replacements within the same ST family include other T8xx variants with different current ratings, such as T812 or T816, provided the voltage rating remains sufficient. Cross-manufacturer equivalents should be verified for matching gate trigger characteristics and thermal performance to ensure circuit compatibility without redesign.
