MAC12SMG

Triacs Overview

The MAC12SMG is a bidirectional triac manufactured by Littelfuse, designed for AC switching applications. It features a TO-220AB through-hole package with three pins. The device supports an RMS on-state current of 12 A and offers a repetitive peak off-state voltage (VDRM) of 600 V. Key electrical parameters include a maximum gate trigger voltage (VGT) of 1.5 V and a maximum gate trigger current (IGT) of 35 mA. The component operates within a temperature range of -40°C to +125°C and has a non-repetitive peak surge current rating of 100 A.

Triacs Feature Summary

• Sensitive gate structure for reliable triggering
• Electrically isolated TO-220AB package
• Glass-passivated junctions for parameter stability

Triacs Applications

• AC motor speed controls
• Lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'MG' against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging options. Ensure the procurement channel provides valid RoHS compliance documentation. Cross-reference the part number with Littelfuse's current product status to confirm availability and active manufacturing status before finalizing orders.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 12 A continuous current capacity are required in a standard TO-220 form factor. The sensitive gate characteristics make it suitable for low-power drive circuits. Verify that the thermal management design accommodates the specified operating temperature range and power dissipation requirements for the intended application environment.

Triacs Part Context

This triac belongs to the MAC series of power semiconductors from Littelfuse. The MAC series is widely used in general-purpose AC control applications. The specific model utilizes a robust silicon chip with glass passivation to ensure long-term reliability and stable performance under varying electrical conditions typical in residential and industrial AC power systems.

Triacs Replacement Considerations

MAC12NG is a documented alternative part number for this component family. Verify compatibility regarding gate sensitivity and voltage ratings before substitution.
