MAC12HCNG

Triacs Overview

The Littelfuse MAC12HCNG is a silicon gate triac rated for 800V peak repetitive off-state voltage and 12A RMS on-state current. It operates within a junction temperature range of -40°C to +125°C and withstands a non-repetitive surge current of 100A. The device features uniform gate trigger currents across quadrants Q1, Q2, and Q3, with a maximum gate trigger voltage of 1.5V and a peak on-state voltage of 1.85V at 17A. Packaged in a TO-220AB (CASE 221A) format, it offers high commutating di/dt capability and dv/dt immunity at elevated temperatures.

Triacs Feature Summary

• High commutating di/dt and dv/dt immunity at 125°C
• Uniform gate trigger currents in three quadrants
• Glass passivated junctions for reliability

Triacs Applications

• Full-wave AC control applications
• Motor controls
• Heating controls
• Dimmers

Triacs Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the 800V rating variant when sourcing. Confirm RoHS compliance and Pb-free status requirements against project specifications. Ensure thermal management design accommodates the specified junction-to-case thermal resistance values during operation.

Triacs Selection Notes

Select this component for designs requiring robust blocking voltages up to 800V and reliable switching in full-wave AC circuits. Consider the TO-220AB package for through-hole mounting ease. Evaluate thermal derating curves for ambient conditions exceeding standard ratings to ensure safe operating area compliance.

Triacs Part Context

This part belongs to the MAC12HC series, which includes variants with different blocking voltage ratings: MAC12HCDG (400V), MAC12HCMG (600V), and MAC12HCNG (800V). All share identical current ratings and package styles but differ in their peak repetitive off-state voltage capabilities.

Triacs Replacement Considerations

MAC12HCMG and MAC12HCDG are functionally similar triacs within the same series, differing primarily in their maximum blocking voltage ratings of 600V and 400V respectively.
