T3035H-8G

Overview

The T3035H-8G is a high-temperature Triac from the H-Series, manufactured by STMicroelectronics. It operates with an RMS on-state current of 30 A and a symmetrical blocking voltage of 800 V. The device supports a maximum junction temperature of 150 °C and features a non-repetitive surge peak on-state current of 270 A at 20 ms. Gate trigger current (IGT) ranges from 5 mA to 35 mA, while gate trigger voltage (VGT) has a maximum value of 1.3 V. Static dV/dt immunity is specified at a minimum of 2000 V/µs at 150 °C. The component utilizes a D²PAK surface-mount package.

Feature Summary

• Based on ST Snubberless high temperature technology for robust commutation
• Provides enhanced thermal management in a compact D²PAK package
• Offers high noise immunity and static dV/dt levels up to maximum junction temperature
• Supports three triggering quadrants for versatile control applications

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 suffix when purchasing. The standard tube version is designated as T3035H-8G, while the tape and reel variant carries the -TR suffix. Confirm that the received components match the required packaging format for your assembly process. Ensure compliance with ECOPACK2 environmental standards during procurement.

Selection Notes

Select this component for designs requiring high current handling in a surface-mount footprint. The D²PAK package facilitates heatsink size reduction compared to through-hole alternatives. Consider the thermal resistance characteristics when designing PCB copper pads. Verify that the application voltage does not exceed the 800 V repetitive peak off-state rating.

Part Context

This Triac belongs to the H-Series, which focuses on high noise immunity and robust dynamic turn-off commutation. It shares core electrical specifications with other variants like the T3035H-8T but differs in physical packaging. The series is engineered for industrial control and home appliance environments demanding reliable operation under heavy AC loads.

Replacement Considerations

The T3035H-8T serves as a pin-compatible alternative housed in a TO-220AB package. Designers requiring surface mount technology must retain the D²PAK form factor. Verify thermal dissipation requirements if substituting between packages due to differing thermal resistance values.
