T835H-6G-TR

Overview

The T835H-6G-TR is a surface-mount bidirectional triac from STMicroelectronics, housed in a TO-263 (D2PAK) package with three pins. It features an RMS on-state current rating of 8 A and a repetitive peak off-state voltage of 600 V. The device supports a non-repetitive surge current of 84 A and operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a maximum gate trigger current of 35 mA, a maximum gate trigger voltage of 1 V, and a peak on-state voltage of 1.5 V. The component exhibits a low holding current of 35 mA and a repetitive peak off-state leakage current of 5 μA.

Feature Summary

Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration required for automated assembly processes. Ensure that the selected variant matches the necessary voltage and current ratings for the target application circuit. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is required for general-purpose AC power switching applications. The 600 V rating suits standard mains voltage environments, while the 8 A current capacity handles moderate load requirements. Consider the thermal resistance characteristics of the D2PAK package for heat dissipation planning in enclosed designs.

Part Context

This device belongs to the T835H series of Snubberless Triacs designed for robust performance in AC switching duties. The H-series designation indicates enhanced high-temperature capabilities up to 150°C. The product line utilizes clip bonding technology to achieve low thermal resistance, ensuring reliable operation under demanding electrical conditions.

Replacement Considerations

Direct substitutes within the same family include T835H-6I for through-hole mounting or T835H-8G-TR for higher voltage ratings. Verify pinout compatibility and thermal management requirements when transitioning between different package types or voltage variants.
