T1035H-6I

Triacs Overview

The T1035H-6I is a medium current Triac from the H-Series, rated for 600 V repetitive peak off-state voltage and 10 A RMS on-state current. It operates within a junction temperature range of -40 °C to +150 °C and features a non-repetitive peak surge current capacity of 105 A. The device exhibits a maximum on-state voltage of 1.5 V and a holding current of up to 35 mA. Gate triggering requirements are specified at 1 V and 35 mA, with an off-state leakage current limited to 5 uA. Packaged in a TO-220-3 through-hole configuration, it supports high-temperature applications.

Triacs Feature Summary

• Snubberless technology providing robust dynamic turn-off commutation and high noise immunity
• Internal ceramic pad enabling 2500 VRMS voltage insulation between terminals and heatsink
• High three-quadrant commutation capability suitable for inductive loads

Triacs Applications

• General purpose mains power AC switching
• Static relays and heating regulation circuits
• Induction motor starting circuits
• Phase control operations in light dimmers
• Appliance motor speed controllers

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number T1035H-6I with official STMicroelectronics documentation. Confirm RoHS compliance status and specific package markings against the datasheet specifications. Ensure the supplier provides valid traceability records for the TO-220-3 insulated package variant.

Triacs Selection Notes

Select this component for designs requiring high-temperature operation up to 150 °C and enhanced thermal management via clip bonding. The Snubberless feature simplifies circuit design for inductive loads by eliminating external RC snubber networks. Verify that the 600 V blocking voltage and 10 A current ratings align with the specific load requirements of the application.

Triacs Part Context

This Triac belongs to the T10xxH series, which includes variants like the T1035H. These components are designed for general-purpose mains power AC switching. The series utilizes internal ceramic pads for insulation and offers low thermal resistance, making them suitable for compact designs where heat dissipation is critical.

Triacs Replacement Considerations

Direct substitutes include other STMicroelectronics Triacs from the same H-Series family, such as the T835H-6I or T2035H-6I, provided their current and voltage ratings meet the system requirements. Verify pinout compatibility and insulation characteristics when considering alternatives.
