T2035H-600TRG

Overview

The STMicroelectronics T2035H-600TRG is a Snubberless TRIAC rated for 600 V repetitive peak off-state voltage and 20 A RMS on-state current. It operates within a junction temperature range of -30°C to 150°C and utilizes a TO-220 package with through-hole mounting. Key electrical parameters include a maximum non-repetitive surge current of 200 A at 50 Hz, a gate trigger current (Igt) maximum of 35 mA, and a gate trigger voltage (Vgt) maximum of 1.3 V. The device maintains a holding current (Ih) maximum of 35 mA. This component belongs to the H-series designed for general-purpose AC switching applications.

Feature Summary

• Snubberless design eliminates the need for external RC snubber circuits under defined limits
• High static dV/dt immunity reduces risk of false turn-on
• Extended thermal capability supports operation up to 150°C junction temperature

Applications

• General purpose mains power AC switching
• Lighting control systems
• Motor speed control applications

Procurement Notes

Verify component authenticity through authorized distributors as this part number is marked as obsolete. Confirm that the TO-220 package variant matches your PCB footprint requirements. Check RoHS compliance status against specific project regulations. Ensure replacement components like BTA20-600CWRG are validated for thermal and electrical compatibility before integration into existing designs.

Selection Notes

Select this component when high commutation capability and reduced bill-of-materials complexity are required. The Snubberless feature simplifies circuit design by removing external protection components. Verify that the 600 V rating meets system voltage peaks. Consider the TO-220 package size constraints and thermal dissipation needs relative to the 20 A current rating in your specific application environment.

Part Context

This device is part of the T2035H series from STMicroelectronics, which focuses on robust TRIAC solutions for industrial and consumer AC loads. The H-series designation indicates enhanced thermal performance compared to standard variants. It serves as a direct functional replacement for older TRIAC models requiring similar current and voltage ratings without snubber networks.

Replacement Considerations

BTA20-600CWRG is listed as a similar alternative. Validate pinout compatibility and thermal resistance characteristics between the original and substitute parts.
