T810-800G-TR

Overview

The T810-800G-TR is a logic-level triac from STMicroelectronics, rated for an RMS on-state current of 8 A and a repetitive peak off-state voltage of 800 V. It operates within a junction temperature range of -40°C to +150°C and features a low gate trigger current of 10 mA, enabling direct microcontroller interfacing. The device utilizes a D2PAK surface-mount package and complies with ECOPACK2 environmental standards, ensuring halogen-free construction.

Feature Summary

• Logic-level sensitivity allows direct control by microcontrollers without additional driver circuitry
• Optimized for high EMI constraints in general-purpose AC switching applications
• Halogen-free molding compound meets UL94 flammability standard level V0

Applications

• On/off or phase angle control in general purpose AC switching with resistive loads
• Automated manufacturing designs requiring compact SMT footprints
• AC power supply front-end circuits with input rectifier bridge topologies

Procurement Notes

Verify the exact part number against official STMicroelectronics documentation before procurement. Confirm that the suffix 'G-TR' corresponds to the specific tape-and-reel packaging configuration required for your automated assembly line. Ensure compatibility with the intended thermal management solution given the 150°C maximum junction temperature rating.

Selection Notes

Select this component when designing systems requiring direct MCU drive capability for AC loads. The 8A current rating suits moderate power applications, while the 800V blocking voltage provides adequate margin for standard mains voltages. Consider the D2PAK package dimensions for PCB layout constraints and verify thermal dissipation requirements under continuous load conditions.

Part Context

This device belongs to the STMicroelectronics T-Series Triacs, which are specifically engineered for logic-level triggering. The series emphasizes ease of integration with modern digital controllers and improved electromagnetic interference performance compared to standard triacs.

Replacement Considerations

Direct substitutes include other 8A logic-level triacs in D2PAK packages such as the T810T-8G. Verify pinout compatibility and ensure equivalent electrical ratings for voltage and current handling before substitution.
