T2535T-8G-TR

Overview

The T2535T-8G-TR is a Snubberless Triac in the D²PAK surface-mount package, rated for 25 A RMS on-state current and 800 V repetitive peak off-state voltage. It supports non-repetitive surge currents up to 210 A and operates with junction temperatures ranging from -40 °C to +150 °C. The device features a maximum gate trigger current of 35 mA and offers high static dV/dt noise immunity exceeding 1000 V/µs at elevated temperatures. Designed for general-purpose AC switching, it eliminates the need for external snubber circuits under specified limits.

Feature Summary

• Snubberless technology enables operation without external RC circuits
• High thermal stability with a maximum junction temperature of 150 °C
• Robust dynamic turn-off commutation performance
• High noise immunity against false triggering

Applications

• General purpose AC line load control
• AC induction and universal motor control
• Heating applications such as water heaters and e-bidets
• Power tools and home appliances including cookers and ovens
• Inrush current limiting and overvoltage crowbar protection

Procurement Notes

Verify the specific ordering suffix TR indicates tape and reel packaging rather than tube configuration. Confirm that the component meets ECOPACK2 environmental standards, ensuring compliance with RoHS directives and halogen-free requirements. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring automated assembly due to its SMD D²PAK form factor. Ensure the application respects the 25 A RMS limit at a case temperature of 121 °C. Verify that the circuit design accommodates the 900 V non-repetitive surge capability and utilizes the three-quadrant triggering functionality for reliable phase angle control.

Part Context

This part belongs to the ST T-Series Triacs, which utilize proprietary Snubberless technology to simplify AC switch designs. The T2535T-8G variant specifically targets medium-current applications within the 25 A range. It serves as the surface-mount equivalent to through-hole versions, providing similar electrical characteristics optimized for constrained environments in home appliances.

Replacement Considerations

Direct replacements include the T2535T-8G in tube packaging or the T2535T-8I insulated TO-220AB variant. For lower current requirements, the T2035T-8G offers comparable Snubberless performance in the same D²PAK package but with a 20 A rating.
