T2050H-6G-TR

Overview

The STMicroelectronics T2050H-6G-TR is a bidirectional triac in the H-series, packaged in TO-263 (D2PAK) for surface-mount installation. It features a 20 A RMS on-state current and a 600 V repetitive peak off-state voltage. The device supports an operating temperature range from -40°C to +150°C. Key electrical parameters include a maximum gate trigger current of 50 mA, a maximum gate trigger voltage of 1 V, and a peak on-state voltage of 1.5 V. It withstands a non-repetitive surge current of 210 A and has a maximum holding current of 75 mA.

Feature Summary

• Snubberless technology enables high noise immunity and simplified circuit design without external RC snubbers.
• Optimized for reliable operation at elevated junction temperatures up to 150°C.
• High three-quadrant commutation capability ensures robust performance with inductive loads.

Applications

• Control of universal motors in power tools
• Inductive load switching in major home appliances
• AC power control circuits requiring high thermal stability

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with the target PCB footprint for the TO-263 package. Confirm that the intended application does not exceed the specified thermal or electrical limits defined in the datasheet.

Selection Notes

Select this component when a surface-mount solution is required for 20 A AC switching applications. The D2PAK package offers lower thermal resistance compared to through-hole alternatives like TO-220. Consider the 600 V rating for standard mains voltage applications and verify gate drive capabilities match the 50 mA trigger requirement.

Part Context

This part belongs to the T2050H series of high-temperature triacs from STMicroelectronics. The 'G' suffix typically denotes the D2PAK/TO-263 surface-mount package variant, while the '-TR' indicates tape-and-reel packaging for automated assembly. It shares core electrical characteristics with other members of the H-series but differs in physical form factor.

Replacement Considerations

Direct substitutes within the same family include T2050H-6G (tube packaging). For through-hole requirements, T2050H-6T serves as a pin-compatible alternative in the TO-220 package. Higher current variants such as T3050H-6G are available if increased amperage is needed.
