T2035H-6I

Overview

The T2035H-6I is a medium current Triac from the STMicroelectronics H-Series, designed for general-purpose mains power AC switching. It features an RMS on-state current of 20 A and a repetitive peak off-state voltage (VDRM) of 600 V. The device supports a non-repetitive surge current of 210 A and operates within a junction temperature range of -40 °C to +150 °C. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1 V, and a gate trigger current of 35 mA. It exhibits a peak on-state voltage of 1.5 V and a low off-state leakage current of 6.2 uA at VDRM. Packaged in a TO-220AB-3 through-hole configuration, it integrates an internal ceramic pad providing 2500 V RMS insulation.

Feature Summary

• Snubberless design eliminates the need for external RC snubber circuits under defined limits
• High three-quadrant commutation capability ensures reliable turn-off performance
• Internal ceramic pad provides enhanced voltage insulation between tab and terminals
• Clip bonding technology delivers low thermal resistance for efficient heat dissipation

Applications

• General purpose mains power AC switching
• Phase angle control circuits requiring high commutation capability
• Solid state relays and motor speed control applications

Procurement Notes

Verify the specific suffix 'I' confirms the TO-220AB insulated package variant. Confirm RoHS compliance status via the official datasheet as regulatory requirements evolve. Check for any Product Change Notifications that may affect pinout or material composition before finalizing procurement orders.

Selection Notes

Select this component when a 20 A RMS current rating and 600 V blocking voltage are required in a through-hole insulated package. Ensure the application respects the 150 °C maximum junction temperature limit. Verify that the load characteristics remain within the specified dV/dt and di/dt commutation capabilities to prevent false triggering.

Part Context

This part belongs to the STMicroelectronics H-Series Triacs, which are engineered for high-temperature operation up to 150 °C. The series utilizes Snubberless technology to simplify circuit design by removing external snubber components. The H-Series offers improved thermal performance compared to traditional thyristors, allowing for reduced heatsink sizes in compact power electronics designs.

Replacement Considerations

Direct substitutes include other STMicroelectronics H-Series Triacs with matching ratings, such as the T835H-6I for lower current needs or the T3035H-6I for higher capacity. Ensure replacement parts maintain the same TO-220AB insulated package form factor and 600 V voltage rating.
