T1050H-6T

Triacs Overview

The STMicroelectronics T1050H-6T is a high-temperature Triac belonging to the H-series, designed for general-purpose mains power AC switching applications. It features a rated RMS on-state current of 20 A and a repetitive peak off-state voltage of 600 V. The device supports a maximum junction temperature of 150 °C and operates within a range of -40 °C to +150 °C. Packaged in TO-220AB for through-hole mounting, it exhibits a non-repetitive peak on-state current of 210 A. Key electrical parameters include a maximum gate trigger current of 50 mA, a maximum holding current of 75 mA, and a typical on-state voltage of 1.5 V.

Triacs Feature Summary

• High thermal capability with a maximum junction temperature rating of 150 °C
• Snubberless design enabling direct drive from logic devices without external RC snubber networks
• Robust commutation performance suitable for highly inductive loads

Triacs Applications

• General purpose mains power AC switching
• Solid state relays
• Motor speed control circuits

Triacs Procurement Notes

Verify the specific suffix '6T' against official datasheets to confirm the TO-220AB through-hole package variant. Ensure the procurement channel provides traceable documentation confirming compliance with RoHS standards and UL certification file E81734. Cross-reference the part number with manufacturer databases to distinguish between tube and reel packaging options available for this specific series.

Triacs Selection Notes

Select the T1050H-6T when an application requires a 20 A RMS current rating combined with operation at elevated temperatures up to 150 °C. This component is appropriate for designs needing Snubberless functionality to simplify circuit topology. Consider the TO-220AB package for through-hole assembly requirements where higher thermal dissipation is necessary compared to surface-mount alternatives.

Triacs Part Context

This component belongs to the T10xxH-6I/H Triac series, which utilizes internal ceramic pads for voltage insulation rated at 2500 V rms. The series is characterized by low thermal resistance achieved through clip bonding technology. These devices are engineered to provide reliable performance in demanding AC switching environments while maintaining compliance with international safety standards.

Triacs Replacement Considerations

Direct replacements within the same family include the T2050H-6T, which shares identical electrical ratings but may differ in specific thermal characteristics or pinout configurations depending on the exact manufacturing revision. Verify compatibility before substitution.
