MAC12HCM

Triacs Overview

The MAC12HCMG is a silicon bidirectional thyristor (Triac) designed for full-wave AC control applications. It features an on-state RMS current rating of 12 A at a case temperature of 80°C and offers peak repetitive off-state voltages up to 800 V. The device provides high surge current capability of 100 A and maintains uniform gate trigger currents across quadrants Q1, Q2, and Q3. Packaged in the industry-standard TO-220AB format, it includes glass passivated junctions for reliability and operates within a junction temperature range of -40°C to +125°C.

Triacs Feature Summary

• High commutating di/dt and immunity to dv/dt at elevated temperatures
• Minimizes snubber network requirements for circuit protection
• Uniform gate trigger characteristics across multiple operating quadrants

Triacs Applications

• Motor controls
• Heating controls
• Dimmers

Triacs Procurement Notes

Verify the specific voltage suffix when ordering; 'M' indicates the 600 V variant. Confirm RoHS compliance and Pb-free status as standard for this product line. Ensure thermal management aligns with the specified 80°C case temperature limit for rated current operation.

Triacs Selection Notes

Select based on required blocking voltage: D for 400 V, M for 600 V, or N for 800 V. Consider the 12 A RMS rating against load requirements and derate current according to case temperature curves. Verify gate trigger current compatibility with the driving circuit across all expected operating quadrants.

Triacs Part Context

This component belongs to the MAC12HC series of Triacs manufactured by onsemi. The series includes variants with different voltage ratings (MAC12HCDG, MAC12HCMG, MAC12HCNG) sharing identical current handling and package specifications. It is part of the broader portfolio of silicon gate-controlled devices for AC power switching.

Triacs Replacement Considerations

Direct substitutes include other 12 A, 600 V Triacs in TO-220 packages from compatible manufacturers. Ensure equivalent gate trigger current and holding current specifications are met. Verify that the replacement device supports the required commutating di/dt and dv/dt ratings for the specific application environment.
