T1250H-6G-TR

Triacs Overview

The T1250H-6G-TR is a Snubberless Triac manufactured by STMicroelectronics, designed for general-purpose mains power AC switching. It features a 600 V repetitive peak off-state voltage and an RMS on-state current rating of 12 A. The device supports a non-repetitive surge current of 126 A at 50/60 Hz. It operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a maximum gate trigger current of 50 mA and a maximum gate trigger voltage of 1 V. The component is housed in a D2PAK (TO-263) surface-mount package with three pins.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC snubber networks
• High thermal performance enabled by clip bonding technology
• Robust commutation capability across multiple operating quadrants

Triacs Applications

• General purpose mains power AC switching
• Industrial motor control circuits
• Solid state relay implementations

Triacs Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required thermal and electrical specifications. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and traceability.

Triacs Selection Notes

Select this component for applications requiring high-temperature operation up to 150°C without external snubber circuits. Ensure the gate drive circuit can supply the specified 50 mA trigger current. Verify that the load current remains within the 12 A RMS limit and that transient surges do not exceed the 126 A rating.

Triacs Part Context

This part belongs to the T12xxH series of medium-current triacs from STMicroelectronics. The H-series designation indicates enhanced high-temperature capabilities compared to standard variants. It shares architectural similarities with the T1235H but differs in gate sensitivity and holding current characteristics.

Triacs Replacement Considerations

Direct substitutes include the T1250H-6G in tube packaging or the T1250-600G-TR if lower temperature ratings are acceptable. Verify pinout compatibility and thermal resistance values when considering alternative packages.
