T835H-6G

Overview

The T835H-6G is a Snubberless™ Triac from STMicroelectronics, rated for 600 V repetitive peak off-state voltage and 8 A RMS on-state current. It operates within a junction temperature range of -40°C to +150°C and utilizes a D2PAK surface-mount package. Key electrical parameters include a maximum non-repetitive surge current of 84 A, an on-state voltage of 1.5 V, and a gate trigger voltage of 1 V. The device features low thermal resistance through clip bonding and provides 2500 V RMS internal insulation via a ceramic pad.

Feature Summary

• Snubberless design eliminates the need for external RC snubber circuits in general-purpose AC switching applications
• High commutation capability supports reliable turn-off in three-quadrant operation
• Integrated ceramic pad provides 2500 V RMS voltage isolation between terminals and heatsink

Applications

• General purpose mains power AC switching
• On/off control functions in value-sensitive appliances
• Phase angle control circuits requiring high commutation capability

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official STMicroelectronics documentation. Confirm that the D2PAK package matches the required PCB footprint and thermal management specifications. Ensure compliance with RoHS directives and check for specific REACH SVHC status updates prior to integration into production assemblies.

Selection Notes

Select this component when a surface-mount solution is required for 8 A AC loads operating up to 600 V. The D2PAK package offers lower thermal resistance compared to through-hole alternatives like TO-220. Consider the 1.5 V on-state voltage for power dissipation calculations and ensure the gate drive circuit can supply at least 35 mA to guarantee reliable triggering under all operating conditions.

Part Context

This device belongs to the T835H series of medium current Triacs designed for robust performance in AC power control. The H-series variant specifically denotes high-temperature capability up to 150°C junction temperature. It shares core electrical characteristics with other members of the family but differs in packaging, offering a compact surface-mount form factor suitable for automated assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout compatibility and thermal resistance values if considering alternative manufacturers' Triacs with similar 8 A/600 V ratings.
