T1050-8G

Triacs Overview

The T1050-8G is a Snubberless Triac from STMicroelectronics, rated for 800 V repetitive off-state voltage and 10 A RMS on-state current. It operates within a junction temperature range of -40 °C to +125 °C and is housed in a D2PAK surface-mount package. Key electrical parameters include a maximum non-repetitive peak on-state current of 105 A, an on-state voltage of 1.55 V, and a gate trigger voltage of 1.3 V. The device features a low off-state leakage current of 5 µA at VDRM and a maximum holding current of 50 mA.

Triacs Feature Summary

• Snubberless design optimized for high commutation performance on inductive loads
• Internal ceramic pad provides insulated tab compliant with UL standards
• Clip bonding technology ensures low thermal resistance

Triacs Applications

• Static relays for AC switching
• Heating regulation systems
• Induction motor starting circuits
• Light dimmers
• Appliance motor speed controllers

Triacs Procurement Notes

Verify the specific ordering suffix (e.g., TR for reel) against the required packaging format. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the D2PAK footprint matches the PCB layout requirements. Check for any recent Product Change Notifications that may affect pinout or material composition before finalizing procurement.

Triacs Selection Notes

Select this component when designing mains power AC switching applications requiring robust performance on inductive loads. The Snubberless architecture eliminates external RC snubber networks, reducing component count. Verify that the 800 V blocking voltage and 10 A current ratings exceed the application's peak demands. Consider the D2PAK package for surface-mount assembly needs.

Triacs Part Context

The T1050-8G belongs to the T10xx series of medium current Triacs from STMicroelectronics. This series is designed for general-purpose mains power AC switching. It shares architectural similarities with the BTA10 and BTB10 series but offers specific package variations. The Snubberless variant distinguishes itself through enhanced commutation capabilities without external buffering components.

Triacs Replacement Considerations

Direct substitutes within the same family include other T1050 variants with different voltage ratings, such as T1050-6G (600V). Cross-series replacements like BTA10 or BTB10 offer similar electrical characteristics but may differ in package type or insulation requirements. Verify compatibility with existing PCB footprints and thermal management designs.
