T3035H-8G-TR

Overview

The T3035H-8G-TR is a high-current Triac from the ST H-Series, housed in a D²PAK package. It features an RMS on-state current of 30 A and a repetitive peak off-state voltage of 800 V. The device supports a maximum junction temperature of 150 °C and operates across three triggering quadrants. Key electrical parameters include a gate trigger current (IGT) maximum of 35 mA, a static dV/dt immunity minimum of 2000 V/µs at 150 °C, and a critical rate of turn-off commutation ((dl/dt)c) minimum of 25 A/ms. The component complies with ECOPACK2 standards.

Feature Summary

• Based on ST Snubberless high temperature technology for robust performance
• Provides enhanced thermal management suitable for compact designs
• Offers high noise immunity and robust dynamic turn-off commutation up to maximum junction temperature

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 TR indicates tape and reel packaging containing 1000 units per base quantity. Confirm that the component meets ECOPACK2 environmental compliance requirements. Ensure the design accounts for the specified thermal resistance values when sizing heatsinks or copper pads for optimal heat dissipation under continuous operation conditions.

Selection Notes

Select this component for applications requiring high current handling in a surface-mount form factor. The D²PAK package facilitates direct bonding to insulated metal substrates or direct bond copper boards. Consider the 150 °C operating limit for environments where standard silicon devices may exceed their thermal ratings. Verify gate drive capabilities against the specified IGT and VGT limits.

Part Context

This part belongs to the T3035H series of Triacs designed for heavy AC loads. The 'G' suffix denotes the D²PAK package, while 'TR' specifies the tape and reel delivery mode. It shares core electrical characteristics with tube-packaged variants like the T3035H-8G but differs in logistics and handling specifications for automated assembly processes.

Replacement Considerations

Direct substitutes within the same family include the T3035H-8G in tube packaging. For different package types, consider the TO-220AB versions such as the T3035H-8T or the insulated T3035H-8I. Ensure any replacement maintains the 800 V blocking voltage and 30 A current rating.
