T1235H-6G

Triacs Overview

The T1235H-6G is a high-temperature Snubberless triac from STMicroelectronics, rated for 12 A RMS current and 600 V blocking voltage. Housed in a D2PAK (TO-263) surface-mount package, it supports a maximum junction temperature of 150°C. Key electrical parameters include a peak on-state voltage of 1.5 V, a gate trigger current of 35 mA, and a surge current rating of 126 A. The device features low thermal resistance via clip bonding and an insulated tab rated at 2500 V rms.

Triacs Feature Summary

• High-temperature operation capability up to 150°C junction temperature
• Snubberless technology providing robust dynamic turn-off commutation
• Insulated tab with 2500 V rms isolation using internal ceramic pad
• Three triggering quadrant compatibility for versatile control

Triacs Applications

• Control of universal motors in industrial equipment
• Heater regulation systems
• Inductive load switching in home appliances

Triacs Procurement Notes

Verify the specific suffix 'G' against the manufacturer datasheet to confirm the tape-and-reel packaging format. Ensure the design accounts for the TO-263 footprint dimensions and thermal requirements. Confirm RoHS compliance status through official documentation before finalizing procurement specifications.

Triacs Selection Notes

Select this component when designing compact AC power switches requiring surface-mount assembly. It is suitable for applications needing high noise immunity and reliable commutation of inductive loads without external snubber circuits. Consider the 12 A current rating and 600 V voltage limit for mains-powered systems.

Triacs Part Context

This part belongs to the T12xxH series of medium-current triacs designed for general-purpose mains power AC switching. The series utilizes ST's high-temperature Snubberless technology to enhance performance in demanding environments while reducing the need for external protection components.

Triacs Replacement Considerations

The T1235H-8G serves as a higher voltage variant within the same series, offering 800 V blocking capability. Designers should verify that the increased voltage rating does not impact thermal or mechanical constraints when substituting.
