T2035H-8G

Overview

The T2035H-8G is a high-temperature Triac from the H-Series, manufactured by STMicroelectronics. It features an RMS on-state current of 20 A and a symmetrical blocking voltage of 800 V. The device supports a maximum junction temperature of 150 °C and utilizes D²PAK packaging for surface mount applications. Key electrical parameters include a gate trigger current (IGT) maximum of 35 mA, a peak off-state voltage of 900 V, and a non-repetitive surge peak on-state current of 210 A at 16.7 ms. The component provides robust dynamic turn-off commutation with a minimum critical rate of rise of on-state current ((dl/dt)c) of 20 A/ms at 150 °C.

Feature Summary

• High noise immunity and robust dynamic turn-off commutation capabilities up to the maximum junction temperature
• Enhanced thermal management through low thermal resistance junction-to-case characteristics
• Snubberless technology enabling direct control of inductive loads without external snubber networks
• Three triggering quadrants operation for versatile gate drive configurations

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
• Lighting and automation I/O control

Procurement Notes

Verify the specific ordering suffix when sourcing components. The standard tube package contains 50 units per base quantity, while the tape and reel variant (-TR) contains 1000 units. Confirm that the procurement matches the required delivery mode for the manufacturing process. Ensure the ECOPACK2 compliance status aligns with environmental regulations applicable to the final assembly.

Selection Notes

Select this component for designs requiring compact SMD solutions with high thermal performance. The D²PAK package facilitates automated manufacturing and reduced heatsink sizes compared to traditional packages. Consider the 150 °C operating limit for environments where ambient temperatures are elevated. Verify that the gate trigger current requirements of the driving circuit fall within the specified 5 mA to 35 mA range across all three quadrants.

Part Context

This Triac belongs to the T2035 series, specifically the H-Series which denotes high noise immunity and robust commutation features. It is part of STMicroelectronics' Snubberless product line designed for industrial control and home appliances. The device is housed in an ECOPACK2 compliant D²PAK package, distinguishing it from through-hole variants like the TO-220AB insulated versions found in the same family.

Replacement Considerations

Direct replacements within the same series include the T2035H-6I or T2035H-8I if through-hole mounting is acceptable. For surface mount alternatives with different current ratings, consider the T3035H-8G for 30 A applications or the T2035T-8G for general purpose usage. Verify pinout compatibility and thermal resistance specifications before substituting.
