T1250-600G-TR

Triacs Overview

The T1250-600G-TR is a Snubberless™ Triac manufactured by STMicroelectronics, designed for general-purpose mains power AC switching in surface-mount applications. It operates within a junction temperature range of -40°C to +125°C and features a TO-263 (D2PAK) package with three pins. Key electrical parameters include a rated RMS on-state current of 12 A, a repetitive peak off-state voltage of 600 V, and a non-repetitive surge current rating of 126 A. The device exhibits a maximum gate trigger current of 50 mA, a maximum holding current of 50 mA, and a peak on-state voltage of 1.55 V.

Triacs Feature Summary

• Snubberless design optimized for high commutation performance on inductive loads
• Insulated tab utilizing internal ceramic pad for enhanced safety isolation
• Low thermal resistance construction via clip bonding technology

Triacs Applications

• Static relays and ON/OFF control functions
• Heating regulation systems
• Induction motor starting circuits
• Phase control operations in light dimmers
• Appliance motor speed controllers

Triacs Procurement Notes

Verify the specific ordering suffix 'TR' to confirm tape-and-reel packaging configuration. Ensure compatibility with RoHS 3 standards and check for any recent Product Change Notifications regarding package dimensions or material composition before finalizing procurement plans.

Triacs Selection Notes

Select this component when surface-mount assembly is required for 12 A AC switching applications. The Snubberless architecture eliminates external RC snubber networks, reducing bill-of-materials complexity. Verify that the 600 V blocking voltage meets circuit requirements and that the D2PAK thermal dissipation capabilities align with the expected load profile.

Triacs Part Context

This part belongs to the T12xx Triac series, which includes variants like the through-hole T1250H-6I. The T1250-600G-TR specifically denotes the surface-mount D2PAK version with a 600 V rating. It shares the Snubberless™ family characteristics but differs from the H-Series (e.g., T1250H-6G) which supports higher junction temperatures up to 150°C.

Triacs Replacement Considerations

Direct pin-compatible alternatives within the same series include other T12xx variants with different voltage ratings or packages. Cross-series replacements may require thermal and mechanical re-evaluation due to differing package footprints.
