T3035H-6G-TR

Overview

The T3035H-6G-TR is a Snubberless TRIAC from STMicroelectronics, rated for 600 V blocking voltage and 30 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 gate trigger current (Igt) of 35 mA, a maximum gate trigger voltage (Vgt) of 1 V, and a maximum holding current (Ih) of 60 mA. Non-repetitive surge currents are specified at 270 A for 50 Hz and 284 A for 60 Hz frequencies.

Feature Summary

• Snubberless technology enables high noise immunity and robust dynamic turn-off commutation without external RC networks.
• Optimized for operation up to 150°C junction temperature, facilitating heatsink size reduction and thermal efficiency.
• Internal ceramic pad provides 2500 VRMS voltage insulation between the terminal and the heatsink.

Applications

• Control of universal motors in power tools
• Inductive load switching in major home appliances
• Industrial control systems requiring high-temperature reliability

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration. Ensure that the selected component meets all relevant RoHS compliance standards required for the target assembly process. Cross-reference the part number with the latest datasheet revisions to validate any potential changes in mechanical dimensions or electrical characteristics.

Selection Notes

Select this component when designing circuits that require surface-mount TRIACs capable of handling high thermal loads without snubber circuits. The 600 V rating suits general mains power applications, while the 30 A current capacity supports heavy AC loads. Consider the D2PAK footprint constraints and verify that the driving circuit can provide the necessary 35 mA gate trigger current for reliable switching.

Part Context

This device belongs to the T3035H H-series family of Triacs, which are specifically engineered for high-temperature performance. The series shares core Snubberless technology features but varies in current ratings and voltage capabilities across different model numbers within the same product line.

Replacement Considerations

The T3035H-6G is the tube-packaged equivalent of this reel version. Other members of the T30xxH series may serve as functional alternatives if current or voltage requirements differ, provided the pinout and thermal characteristics remain compatible.
