T1235H-600TRG

Triacs Overview

The T1235H-600TRG is a high-temperature Snubberless triac from STMicroelectronics, rated for 12 A RMS on-state current and 600 V blocking voltage. It operates within a junction temperature range of -40 °C to +150 °C. The device utilizes clip assembly technology for superior surge handling, with a non-repetitive peak surge current of 140 A at 50 Hz. Key electrical characteristics include a maximum gate trigger current (IGT) of 35 mA, a maximum holding current (IH) of 35 mA, and a minimum static dV/dt of 300 V/µs. Packaged in TO-220AB, it features a thermal resistance from junction to case of 1.2 °C/W.

Triacs Feature Summary

• High commutation switching capabilities and noise immunity levels based on Snubberless technology
• Enhanced performance in power loss and thermal dissipation due to clip assembly technique
• Suitable for hot appliance environments such as cookers, ovens, hobs, electric heaters, and coffee machines

Triacs Applications

• Control of universal motors in home appliances
• Heating regulation circuits
• Induction motor starting circuits
• Phase control operations in light dimmers

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and delivery mode. The 'TRG' designation indicates a tube delivery format for the TO-220AB package. Ensure compatibility with the required PCB footprint and thermal management design before procurement.

Triacs Selection Notes

Select this component when designing systems requiring operation up to 150 °C junction temperature. The TO-220AB package provides robust mechanical stability and effective heat sinking. Consider the 35 mA gate trigger current for driver circuit sizing and verify that the application load does not exceed the 12 A RMS or 140 A surge limits under specified conditions.

Triacs Part Context

This part belongs to the T1235H series of medium current triacs designed for mains power AC switching. The series includes variants with different voltage ratings and packages, such as the D2PAK surface mount option. The T1235H-600TRG specifically denotes the 600 V version in a TO-220AB tube package.

Triacs Replacement Considerations

Compatible replacements within the same family include T1235H-600T for the TO-220AB package and T1235H-600G for the D2PAK package. Verify pinout and thermal resistance specifications when substituting.
