T2035T-8G-TR

Overview

The T2035T-8G-TR is a Snubberless™ 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 non-repetitive surge currents of up to 168 A at 16.7 ms and 160 A at 20 ms. The device operates with a maximum junction temperature of 150 °C and features a minimum static dV/dt of 1000 V/µs at 150 °C. Gate trigger current (IGT) is limited to 35 mA, while the critical rate of rise of on-state current ((dl/dt)c) is specified at 17.5 A/ms at 150 °C without a snubber circuit.

Feature Summary

• High immunity to false turn-on due to elevated static dV/dt ratings
• Robust dynamic turn-off commutation capability optimized for high-temperature environments
• Extended thermal margin allowing continuous operation up to 150 °C junction temperature
• Effective heat dissipation provided by the non-insulated tab design

Applications

• General purpose AC line load switching
• Motor control circuits
• Home appliances
• Heating systems
• Lighting controls

Procurement Notes

Verify the specific ordering code matches the required tape and reel configuration. Confirm that the D²PAK footprint aligns with the recommended stencil definitions provided in the datasheet. Ensure compliance with ECOPACK®2 environmental standards if RoHS and halogen-free requirements are mandatory for the assembly process.

Selection Notes

Select this component when high commutation capability is required without external snubber networks. Evaluate the thermal resistance from junction to case against the expected ambient conditions. Verify that the gate trigger parameters fit within the driving circuit's output capabilities to ensure reliable switching across all three quadrants.

Part Context

This part belongs to the T-Series of Snubberless™ Triacs manufactured by STMicroelectronics. It shares core electrical characteristics with the tube-packaged T2035T-8G variant but utilizes tape and reel packaging for automated surface-mount assembly. The device is designed for general-purpose AC switching applications requiring robust performance under demanding thermal conditions.

Replacement Considerations

The T2035T-8G serves as the direct tube-packaged equivalent. Other members of the T-Series family offer similar Snubberless™ technology but may differ in current ratings or package types such as TO-220AB.
