Triacs datasheet and documents for T1235T-8FP

T1235T-8FP

Triacs Overview

The T1235T-8FP is a Snubberless Triac manufactured by STMicroelectronics, rated for 12 A RMS current and 800 V blocking voltage. It operates within a junction temperature range of -40 °C to +150 °C. The device utilizes a through-hole full pack package compliant with UL standards, featuring 2 kV insulation. Key electrical parameters include a maximum holding current of 40 mA, gate trigger voltage of 1.3 V, and gate trigger current of 35 mA. It supports three-quadrant triggering and offers high static dV/dt and dynamic turn-off commutation capabilities.

Triacs Feature Summary

Through-hole full pack package with UL certified 2 kV insulation
Snubberless operation without external RC circuit when limits are respected
High static and dynamic commutation performance
Three-quadrant triggering capability

Triacs Applications

General purpose AC switching
On/off control functions
Phase angle control applications

Triacs Procurement Notes

Verify component status as the T1235T-8FP is listed as obsolete in official documentation. Confirm availability of alternative packages such as the T1235T-8G (SMD) or T1235T-8I (TO-220AB insulated) if through-hole form factors are required for new designs. Ensure compliance with RoHS and Halogen-free requirements specified for the ECOPACK 2 graded package.

Triacs Selection Notes

Select this component for AC switching applications requiring high commutation capability where through-hole mounting is preferred. The device eliminates the need for snubber circuits under defined limits. Consider thermal management requirements given the 150 °C maximum junction temperature rating. Verify that the 12 A RMS current and 800 V blocking voltage meet the specific load conditions of the target application.

Triacs Part Context

The T1235T-8FP belongs to the T1235T series of medium current Triacs from STMicroelectronics. This series is designed for general-purpose AC switching with high noise immunity. The T1235T-8FP specifically provides a through-hole option compared to surface-mount variants like the T1235T-8G. It shares core electrical characteristics with other members of the family, including high static dV/dt and robust dynamic turn-off commutation.
