MAC16HCN

Triacs Overview

The MAC16HCN is a silicon bidirectional thyristor (Triac) manufactured by onsemi, designed for full-wave AC control applications. It features an industry-standard TO-220 package with a maximum repetitive off-state voltage of 800 V and an RMS on-state 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. Key electrical characteristics include a maximum gate trigger current of 50 mA across quadrants Q1, Q2, and Q3, and a typical holding current of 20 mA.

Triacs Feature Summary

• High commutating di/dt capability and high immunity to dv/dt at elevated temperatures
• Uniform gate trigger currents provided in three operating quadrants (Q1, Q2, and Q3)
• Glass passivated junctions ensure reliability and uniformity

Triacs Applications

• Motor controls
• Heating controls
• Dimmers

Triacs Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the 800 V blocking voltage variant when sourcing components. Confirm RoHS compliance status and Pb-free packaging details through official manufacturer documentation or authorized distributors prior to procurement.

Triacs Selection Notes

Select this component for designs requiring robust AC switching with high surge tolerance. Ensure thermal management accommodates the specified junction-to-case thermal resistance. Verify that the required gate drive current remains within the 50 mA maximum limit for reliable triggering across all operational quadrants.

Triacs Part Context

This part belongs to the MAC16HC family of Triacs from onsemi, which includes variants with different voltage ratings: MAC16HCD (400 V), MAC16HCM (600 V), and MAC16HCN (800 V). All variants share identical current ratings and package dimensions but differ in their peak repetitive off-state voltage capabilities.

Triacs Replacement Considerations

Direct substitutes include MAC16HCMG (600 V) and MAC16HCDG (400 V) if lower voltage ratings are acceptable. Cross-manufacturer equivalents should be evaluated based on matching IT(RMS), VDRM, and TO-220 package compatibility.
