MAC12SNG

Triacs Overview

The MAC12SNG is a bidirectional triac manufactured by Littelfuse, designed for AC power control applications. It features an RMS on-state current rating of 12 A and a non-repetitive peak on-state current of 90 A. The device supports a rated repetitive off-state voltage (VDRM) of 800 V with a maximum off-state leakage current of 10 uA at VDRM. Key electrical parameters include an on-state voltage of 1.85 V, a maximum holding current of 10 mA, and gate trigger specifications of 1.5 V (Vgt) and 5 mA (Igt). It operates within a temperature range of -40 C to +110 C and is housed in a TO-220-3 through-hole package.

Triacs Feature Summary

• Sensitive gate structure enabling reliable triggering with low gate current requirements.

Triacs Applications

• AC motor speed control circuits
• Solid state relay implementations
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific Littelfuse datasheet revision and RoHS compliance status before finalizing procurement. Confirm that the TO-220-3 package dimensions match the target PCB footprint. Ensure thermal management solutions are adequate for the intended operating environment given the 12 A current rating.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 12 A continuous current capacity are required in a standard TO-220 package. Compare gate sensitivity against alternative triacs if driving from low-power logic interfaces. Verify that the 1.85 V on-state voltage meets thermal dissipation constraints for the specific load profile.

Triacs Part Context

This part belongs to the MAC12SN series of sensitive gate triacs from Littelfuse. These devices are engineered for general-purpose AC switching tasks requiring robust performance in industrial and consumer electronics. The MAC12SNG variant specifically denotes the lead-free, halogen-free version compliant with modern environmental standards.

Triacs Replacement Considerations

MAC12NG is a documented alternative within the same family, though it exhibits different gate trigger current characteristics. Verify compatibility regarding gate drive circuitry before substitution.
