T2035H-6T

Overview

The STMicroelectronics T2035H-6T is a medium current triac from the H-Series, rated for 20 A RMS on-state current and 600 V repetitive peak off-state voltage. It features a maximum junction temperature of 150 °C and supports three triggering quadrants with high noise immunity. The device utilizes Snubberless technology to eliminate external RC snubber circuits under specified limits. Key electrical parameters include a gate trigger current of 35 mA, a gate trigger voltage of 1 V, and a non-repetitive surge current rating of 210 A.

Feature Summary

• Snubberless operation capability reduces component count by removing the need for external RC snubber circuits when operating within defined limits.
• High thermal performance allows operation up to a 150 °C maximum junction temperature, enabling heatsink size reduction compared to traditional triacs.
• Internal ceramic pad provides electrical insulation rated at 2500 V RMS for enhanced safety in mains power applications.

Applications

• General purpose mains power AC switching
• Motor control drives
• Heater load control

Procurement Notes

Verify the specific package type upon ordering, as the T2035H-6T designation typically corresponds to surface mount D2PAK packages, whereas TO-220AB insulated versions often carry suffixes like -6I. Confirm RoHS compliance and UL certification status (ref. file E81734) through official datasheets or distributor documentation before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring high commutation capabilities and extended temperature operation up to 150 °C. Ensure the circuit design respects the 600 V blocking voltage and 20 A RMS current ratings. Verify that the application does not require the 2500 V RMS insulation provided by the insulated variants if cost or thermal resistance optimization is prioritized over isolation.

Part Context

This part belongs to the STMicroelectronics T2035H series of Snubberless triacs. The series includes various voltage ratings (600 V, 800 V) and package options (TO-220AB, D2PAK). The T2035H-6T specifically denotes the 600 V variant in a surface mount configuration, distinct from the through-hole insulated T2035H-6I.

Replacement Considerations

Direct substitutes within the same family include T2035H-6G (D2PAK, 600 V) and T2035H-8G (D2PAK, 800 V). For through-hole insulated replacements, consider T2035H-6I. Verify pinout compatibility and thermal resistance differences between surface mount and through-hole packages when substituting.
