T1210T-8G-TR

Triacs Overview

The T1210T-8G-TR is a surface-mount logic-level triac in the D²PAK package, rated for 12 A RMS on-state current and 800 V repetitive peak off-state voltage. It features a maximum junction temperature of 150 °C and requires only 10 mA gate trigger current for direct microcontroller interfacing. The device supports three-quadrant triggering with a maximum gate trigger voltage of 1 V and a holding current of 25 mA. Non-repetitive surge capability reaches 105 A at 25 °C initial junction temperature. Thermal resistance from junction to case is 1.3 °C/W.

Triacs Feature Summary

• Logic-level operation enabling direct control by microcontrollers via low 10 mA gate trigger current
• Extended thermal margin with a maximum operating junction temperature of 150 °C
• High commutation performance optimized for resistive loads and high EMI constraints
• Halogen-free molding compound compliant with UL94 V0 flammability standards

Triacs Applications

• General purpose AC line load switching
• Small home appliances with resistive loads
• Hybrid relays
• Inrush current limiting circuits
• Overvoltage crowbar protection

Triacs Procurement Notes

Verify the specific ordering suffix TR against the manufacturer's official documentation to confirm tape and reel packaging requirements. Ensure that the selected component matches the exact electrical ratings and thermal characteristics specified in the datasheet before finalizing procurement orders.

Triacs Selection Notes

Select this component when designing compact SMT circuits requiring direct MCU control without additional driver stages. Consider the 150 °C junction temperature rating for applications demanding higher thermal margins compared to standard 125 °C devices. Verify PCB copper pad dimensions align with the recommended D²PAK footprint for optimal heat dissipation.

Triacs Part Context

This part belongs to STMicroelectronics' T-series of snubberless triacs designed for general-purpose AC switching. The T1210T-8G variant specifically utilizes the D²PAK surface-mount package to facilitate automated manufacturing processes while maintaining high current handling capabilities.

Triacs Replacement Considerations

The T1210T-8G (tube version) serves as a direct functional equivalent with identical electrical specifications but differs in packaging format. Other members of the T1210T series may offer different voltage ratings or package types.
