MAC16CMG

Triacs Overview

The Littelfuse MAC16CMG is a silicon gate-controlled triac designed for full-wave AC control applications. It features a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 16 A at 80°C case temperature. The device supports a peak non-repetitive surge current of 150 A and operates within a junction temperature range of -40°C to +125°C. Electrical characteristics include a maximum on-state voltage of 1.6 V, a holding current maximum of 40 mA, and a gate trigger current maximum of 35 mA across all quadrants. Packaged in a TO-220AB (Case 221A) format with glass-passivated junctions, it offers high commutating di/dt and immunity to dV/dt.

Triacs Feature Summary

• High commutating di/dt capability and high immunity to dV/dt at 125°C
• Minimizes the need for snubber networks for protection
• Operational in three quadrants: Q1, Q2, and Q3
• Glass passivated junctions ensure reliability and uniformity

Triacs Applications

• Full wave AC motor controls
• Heating controls
• Lighting dimmers

Triacs Procurement Notes

Verify component authenticity by checking the marking system for year, month, assembly site, and lot serial code. Confirm the 'G' suffix indicates a lead-free package compliant with RoHS standards. Ensure the specific voltage rating matches the application requirements, as the 'M' suffix denotes a 600 V blocking voltage variant distinct from the 800 V 'N' version.

Triacs Selection Notes

Select this component when designing circuits requiring a standard industry TO-220 package for ease of thermal management and mounting. Consider the 16 A RMS current rating relative to the expected load and ambient conditions, applying derating curves if operating above 80°C case temperature. Verify that the 600 V blocking voltage meets the peak line voltage requirements of the target AC system.

Triacs Part Context

The MAC16CMG belongs to the MAC16C series of thyristors manufactured by Littelfuse. This series includes variants with different voltage ratings, such as the MAC16CNG which provides an 800 V blocking voltage. Both share identical current ratings and physical packaging, allowing for design flexibility based on voltage stress requirements while maintaining consistent thermal and mechanical integration.

Triacs Replacement Considerations

Direct replacement options include the MAC16CNG, which shares the same current and package specifications but offers an increased 800 V blocking voltage rating. Designers should verify that the higher voltage rating does not impact gate drive compatibility or circuit timing constraints before substituting.
