T2035H-8G-TR

Overview

The T2035H-8G-TR is a high-current Triac in the D²PAK surface-mount package, rated for 20 A RMS on-state current and 800 V repetitive peak off-state voltage. It supports a maximum junction temperature of 150 °C with a non-repetitive surge current capability of 210 A. The device features a maximum gate trigger current of 35 mA and a static dV/dt immunity of at least 2000 V/µs at 150 °C. Thermal resistance from junction to case is 1.0 °C/W maximum. It operates within a temperature range of -40 °C to +150 °C.

Feature Summary

• High noise immunity and robust dynamic turn-off commutation enabled by ST Snubberless technology
• Three triggering quadrants operation for versatile control applications
• ECOPACK2 compliant lead-free packaging with halogen-free molding compound

Applications

• Home automation smart AC plugs
• Water heaters, room heaters, and coffee machines
• AC induction and universal motor control
• Inrush current limiting in AC DC rectifiers
• General purpose AC line load control

Procurement Notes

Verify the specific ordering code T2035H-8G-TR against the manufacturer's datasheet to confirm the tape and reel delivery mode. Ensure that the component selection aligns with the required thermal management strategy for the D²PAK package. Confirm compliance with environmental standards such as ECOPACK2 specifications before finalizing procurement orders.

Selection Notes

Select this component when compact SMD designs require heavy AC load driving capabilities up to 20 A. The D²PAK package facilitates automated manufacturing and reduced heatsink sizes due to enhanced thermal performance. Consider the 150 °C operating limit for high-temperature industrial or appliance environments where traditional triacs may require larger heat sinks.

Part Context

This part belongs to the H-Series Triac family from STMicroelectronics, designed for general-purpose mains power AC switching. The 'H' designation indicates high noise immunity and robust commutation characteristics. The T2035H-8G variant specifically offers 800 V blocking voltage and 20 A current rating in a surface-mount format suitable for space-constrained PCB layouts.

Replacement Considerations

Direct substitutes include other STMicroelectronics Triacs from the same H-Series family with matching current and voltage ratings, such as the T2035H-6 series for lower voltage applications. Verify pinout compatibility and thermal resistance values when replacing with components from different manufacturers.
