T1235H-6G-TR

Triacs Overview

The T1235H-6G-TR is a high-temperature bidirectional triac from STMicroelectronics, rated for 12 A RMS and 600 V blocking voltage. It utilizes Snubberless technology to ensure robust commutation without external RC networks. The device operates within a junction temperature range of -40°C to +150°C and features a TO-263 (D2PAK) surface-mount package. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1 V, and a peak on-state voltage of 1.5 V. It supports three triggering quadrants and offers high static dV/dt noise immunity.

Triacs Feature Summary

• Snubberless design eliminates the need for external snubber circuits, simplifying layout and reducing component count.
• High-temperature capability allows reliable operation in demanding environments up to 150°C junction temperature.
• Robust dynamic turn-off commutation ensures stable performance with inductive loads such as motors and heaters.

Triacs Applications

• AC load switching in home appliances
• Motor control drives
• Heating regulation systems

Triacs Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the ordering part number matches the exact voltage and current ratings required for the target application circuit.

Triacs Selection Notes

Select this component for applications requiring high thermal stability and simplified gate drive circuits. The TO-263 package provides adequate thermal dissipation for 12 A continuous current. Verify that the gate trigger current requirements of the driving circuit align with the specified 35 mA maximum to ensure reliable turn-on.

Triacs Part Context

This device belongs to the H-Series Triacs family, specifically designed for high-temperature industrial and consumer applications. It shares the Snubberless architecture with other members like the T1235H-8I but differs in voltage rating and package type. The series is optimized for compact AC power control solutions.

Triacs Replacement Considerations

Direct replacements must match the 12 A/600V rating and TO-263 package. Consider the T1235H-6G (tube version) for non-reel applications. Verify compatibility with existing PCB footprints and thermal management designs before substitution.
