T1235-6B-TR

Triacs Overview

The T1235-6B-TR is a bidirectional triac from STMicroelectronics, designed for general-purpose mains power AC switching. It features a rated average on-state current of 12 A and a repetitive peak off-state voltage of 600 V. The device utilizes surface-mount technology in a TO-263 (D2PAK) package with three pins. Key electrical parameters include a maximum gate trigger current of 35 mA, a maximum holding current of 35 mA, and a peak on-state voltage of 1.5 V. It operates within a temperature range of -40°C to +125°C and supports non-repetitive surge currents up to 126 A.

Triacs Feature Summary

• Snubberless design optimized for high commutation performance on inductive loads
• Internal ceramic pad provides insulated tab compliant with UL standards
• Logic Level configuration suitable for LED lamp dimmer applications

Triacs Applications

• Static relays
• Heating regulation systems
• Induction motor starting circuits

• Appliance motor speed controllers

Triacs Procurement Notes

Verify the specific suffix '6B' against official STMicroelectronics documentation to confirm exact voltage ratings and package variations. Ensure compatibility with Snubberless™ technology requirements for inductive load control. Confirm RoHS compliance status and lead times through authorized distributors.

Triacs Selection Notes

Select this component for applications requiring medium current AC switching with high noise immunity. The logic level variant is ideal for low-power gate drive circuits, such as those driving LED lamps. Consider thermal management needs given the 12 A rating and D2PAK package constraints.

Triacs Part Context

This part belongs to the T12xx Triac series, which includes BTA12 and BTB12 variants. These devices are engineered for robust performance in mains-powered applications. The series offers both through-hole and surface-mount options, with the T12xx line specifically highlighting Snubberless™ capabilities for simplified circuit design.

Triacs Replacement Considerations

Compatible substitutes within the same family include T1235H-6G and T1235-600G. Verify pinout compatibility and thermal resistance specifications when replacing components in existing designs.
