MAC16HCNG

Triacs Overview

The Littelfuse MAC16HCNG is a silicon gate-controlled triac designed for full-wave AC control applications. It features an on-state RMS current rating of 16 Amperes at a case temperature of 80°C and supports peak non-repetitive surge currents up to 150 Amperes. The device offers blocking voltages ranging from 400V to 800V, with the MAC16HCNG variant rated specifically at 800V VDRM/VRRM. It operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220 package (CASE 221A) for through-hole mounting.

Triacs Feature Summary

• High commutating di/dt capability and high immunity to dv/dt at 125°C
• Uniform gate trigger currents across Quadrants Q1, Q2, and Q3
• Glass passivated junctions for enhanced reliability and parameter uniformity

Triacs Applications

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

Triacs Procurement Notes

Verify the specific voltage suffix 'N' corresponds to the required 800V rating during procurement. Confirm that the ordering part number includes the 'G' suffix to ensure lead-free and RoHS compliance as specified in the datasheet. Cross-reference the manufacturer's latest documentation to confirm current production status and any potential specification updates prior to finalizing orders.

Triacs Selection Notes

Select the MAC16HCNG when an 800V blocking voltage is required for the application. Ensure the thermal design accommodates the 16A RMS rating at a maximum case temperature of 80°C. Verify that the circuit can handle the 150A surge current capability without exceeding the device's I²t fusing consideration limits. Consider the TO-220 package dimensions for PCB layout constraints.

Triacs Part Context

The MAC16HCNG belongs to the MAC16HCxG family of thyristors manufactured by Littelfuse. This series includes variants with different voltage ratings: MAC16HCDG (400V), MAC16HCMG (600V), and MAC16HCNG (800V). All variants share identical current ratings, package styles, and general electrical characteristics, differing primarily in their peak repetitive off-state voltage capabilities.

Triacs Replacement Considerations

Direct functional replacements within the same Littelfuse family include MAC16HCDG and MAC16HCMG, provided the lower voltage ratings are acceptable for the circuit. Ensure the substitute component meets the 800V requirement if replacing the MAC16HCNG specifically.
