T1210T-8T

Triacs Overview

The T1210T-8T is a logic level triac manufactured by STMicroelectronics, rated for 12 A RMS on-state current and 800 V repetitive peak off-state voltage. Housed in a TO-220 through-hole package, it supports a maximum junction temperature of 150°C and operates within a range of -40°C to +150°C. Key electrical parameters include a gate trigger current of 10 mA, a gate trigger voltage of 1.3 V, and a holding current of 15 mA. The device features a surge current rating of 95 A, a peak on-state voltage of 1.55 V, and a peak gate power dissipation of 1 W.

Triacs Feature Summary

• Logic level design enabling direct microcontroller driving with low gate current requirements
• Three-quadrant triggering capability for versatile AC switching applications
• ECOPACK2 compliant packaging ensuring environmental safety standards

Triacs Applications

• On/off or phase angle control in general purpose AC switching
• Resistive load management in AC circuits
• Motor speed control systems utilizing universal motors

Triacs Procurement Notes

Verify the specific suffix 'T' corresponds to the TO-220 through-hole configuration rather than surface mount variants like 'G'. Confirm that the component meets ECOPACK2 compliance requirements if environmental regulations are critical. Ensure the selected part number aligns with the required 12A current rating and 800V blocking voltage for the intended circuit design.

Triacs Selection Notes

Select this component when a medium-current triac requires direct MCU interfacing without additional driver circuitry. The 10 mA gate trigger current simplifies logic interface design compared to standard triacs. Consider the TO-220 package for thermal management needs in through-hole PCB layouts where compact SMD solutions are not feasible.

Triacs Part Context

This device belongs to STMicroelectronics' T-Series Triac family, which is optimized for high EMI constraints and general-purpose AC switching. The T1210T-8T specifically addresses applications requiring robust performance in resistive loads while maintaining compatibility with modern low-power control logic.

Triacs Replacement Considerations

The T1210T-8FP is an insulated variant within the same series offering UL certified insulation but utilizes a different package type. Surface mount equivalents such as the T1210T-8G provide identical electrical characteristics but require SMT assembly processes.
