T1050H-6I

Triacs Overview

The T1050H-6I is a medium current Triac from the H-Series, rated for 10 A RMS and 600 V blocking voltage. It supports junction temperatures up to 150 °C and features an insulated tab with 2500 V rms isolation via an internal ceramic pad. Key electrical parameters include a maximum holding current of 75 mA, gate trigger voltage of 1 V, and gate trigger current of 50 mA. The device exhibits a forward voltage drop of 1.5 V and leakage current of 5 µA at VDRM. Packaged in TO-220-3 for through-hole mounting, it offers low thermal resistance through clip bonding and high three-quadrant commutation capability.

Triacs Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number T1050H-6I with official STMicroelectronics documentation. Confirm package type is TO-220-3 and series is H-Series. Ensure compliance with RoHS (2002/95/EC) directives and UL certification file E81734 requirements before integration into final assemblies.

Triacs Selection Notes

Select this component for applications requiring general purpose AC switching with medium current handling. The 600 V rating suits standard mains voltages. The insulated tab design facilitates safe mounting on heatsinks without additional insulators. Verify that the 50 mA gate trigger current aligns with the driving circuit capabilities.

Triacs Part Context

This Triac belongs to the T10xxH-6I series, which includes similar variants like the T1035H. These devices are designed for robust performance in AC power control environments. The H-Series designation indicates specific thermal and commutation characteristics optimized for industrial and consumer appliance applications requiring reliable switching under varying load conditions.

Triacs Replacement Considerations

Direct substitutes within the same family include the T1035H. Verify pinout compatibility and thermal specifications when replacing components. Ensure the alternative device meets the same 600 V blocking voltage and 150 °C junction temperature requirements for equivalent system performance.
