MAC15MG

Triacs Overview

The Littelfuse MAC15MG is a three-terminal triac in a TO-220AB package, rated for 600V peak repetitive off-state voltage and 15A RMS on-state current at 80°C. It features uniform gate trigger currents across three operating modes with a maximum of 35mA. The device offers high commutating di/dt of 9.0 A/ms minimum at 125°C and critical rate of rise of off-state voltage (dv/dt) of 250 V/µs. Operating junction temperature ranges from -40°C to +125°C.

Triacs Feature Summary

• Designed for full-wave AC control applications requiring high noise immunity
• Operates in Quadrants Q1, Q2, and Q3 with uniform gate trigger characteristics
• Minimizes snubber network requirements due to high dv/dt immunity

Triacs Applications

• High performance full-wave AC control circuits
• Industrial motor speed controls
• Solid state relays

Triacs Procurement Notes

Verify the specific suffix 'G' indicates lead-free packaging when ordering. Confirm the 'M' designation corresponds to the 600V blocking voltage rating rather than the 800V variant. Ensure thermal management aligns with the specified 15A RMS rating at an 80°C case temperature.

Triacs Selection Notes

Select this component for applications requiring robust commutation capabilities and high noise immunity. Verify that the system's peak voltage does not exceed 600V. Consider the thermal resistance values for heatsink design if operating near the maximum current limits.

Triacs Part Context

This part belongs to the MAC15M/N series of thyristors manufactured by Littelfuse. It utilizes the industry-standard TO-220AB (Case 221A) package style. The device is Pb-Free and RoHS compliant, suitable for modern manufacturing processes.

Triacs Replacement Considerations

MAC15NG serves as a higher voltage alternative within the same series, offering 800V blocking capability while maintaining identical current ratings and package dimensions.
