T1235T-8T

Triacs Overview

The T1235T-8T is a 12 A Snubberless Triac housed in a TO-220AB through-hole package. It supports on/off and phase angle control for general-purpose AC switching applications requiring high commutation capability. The device operates with a maximum junction temperature of 150 °C and features three triggering quadrants. It complies with ECOPACK2 environmental standards, ensuring RoHS and halogen-free construction.

Triacs Feature Summary

• Snubberless operation allows use without external RC circuits when datasheet limits are respected
• High static and dynamic commutation performance for robust switching
• Three-quadrant triggering capability for versatile gate control

Triacs Applications

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

Triacs Procurement Notes

Verify the specific ordering code T1235T-8T against official STMicroelectronics documentation to confirm the TO-220AB through-hole package variant. Ensure design parameters align with the defined snubberless limits to maintain device integrity during operation.

Triacs Selection Notes

Select this component for medium current AC switching where high commutation capability is required. The extended 150 °C junction temperature rating provides thermal margin for compact designs. Verify that the application does not exceed the specified voltage and current limits for snubberless operation.

Triacs Part Context

This part belongs to the T-Series of Snubberless Triacs from STMicroelectronics. It shares core technology with variants like T1235T-8I and T1635T-8T but differs in packaging and insulation specifications. The series emphasizes high noise immunity and reduced component count by eliminating snubber circuits.

Triacs Replacement Considerations

Direct substitutes include other T1235T-8x variants with compatible packages. Cross-model replacements within the T-Series require verification of package type (TO-220AB vs D²PAK) and insulation requirements (insulated vs non-insulated tab).
