T1235H-6T

Triacs Overview

The T1235H-6T is a 12 A, 600 V Triac from STMicroelectronics' H-Series, housed in a TO-220AB through-hole package. It features a maximum junction temperature of 150 °C and utilizes Snubberless technology for high noise immunity and robust dynamic turn-off commutation. Key electrical parameters include a peak on-state voltage of 1.5 V, a maximum gate trigger current (Igt) of 35 mA, and a holding current (Ih) of 35 mA. The device supports a surge current rating of 126 A and operates within a temperature range of -40 °C to +150 °C.

Triacs Feature Summary

• Snubberless design eliminates the need for external RC snubber circuits in many applications.
• High static dV/dt and dynamic turn-off commutation capabilities ensure reliable operation with inductive loads.
• Internal ceramic pad provides 2500 V RMS insulation between the terminal and the heatsink.

Triacs Applications

• General purpose mains power AC switching
• Static relays and heating regulation
• Induction motor starting circuits

Triacs Procurement Notes

Verify the specific suffix 'T' indicates the TO-220AB through-hole package variant. Confirm RoHS compliance status and check for any recent Product Change Notifications (PCN) regarding manufacturing site changes or material updates before finalizing procurement orders.

Triacs Selection Notes

Select this component when a medium-current Triac requires high thermal stability up to 150 °C. The Snubberless feature makes it suitable for inductive loads where high commutation performance is critical. Ensure the application voltage does not exceed the 600 V repetitive peak off-state voltage rating.

Triacs Part Context

This part belongs to the T12xxH series, which offers enhanced thermal management compared to standard Triacs. The H-Series is designed for compact drives of heavy AC loads, allowing for reduced heatsink sizes while maintaining robust performance in industrial control and home appliance environments.

Triacs Replacement Considerations

Direct pin-compatible replacements within the same family include T1235H-8T (800 V version). Other variants like T1235H-6G (surface mount D2PAK) share similar electrical characteristics but differ in package type.
