MAC15-8G

Triacs Overview

The Littelfuse MAC15-8G is a bidirectional triac thyristor designed for AC switching applications. It features an average on-state current rating of 15A and supports a repetitive peak off-state voltage (VDRM) of 600V. The device is housed in a TO-220AB through-hole package with three pins. Key electrical parameters include a maximum gate trigger current of 75mA, a gate trigger voltage of 2.5V, and a peak on-state voltage of 1.6V. It withstands a surge current of 150A and operates within a temperature range of -40°C to +125°C.

Triacs Feature Summary

• Integrated glass-passivated junctions ensure long-term parameter stability and reliability under thermal stress.
• High dv/dt capability provides immunity against false triggering during rapid voltage transients.
• Electrically isolated TO-220AB package eliminates the need for external insulators during mounting.

Triacs Applications

• AC motor speed control circuits
• Solid-state relay designs
• Lighting dimmer switches

Triacs Procurement Notes

Verify the specific suffix configuration when ordering, as Littelfuse utilizes alphanumeric codes to denote voltage ratings and packaging variations. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to integration into regulated assemblies.

Triacs Selection Notes

Select this component for circuits requiring 600V blocking capability and 15A continuous load handling. Ensure the driving circuit can supply at least 75mA gate current to guarantee reliable turn-on across the full operating temperature range.

Triacs Part Context

This part belongs to the MAC15 series of high-current triacs from Littelfuse. The series is engineered for robust performance in industrial and consumer power control environments, offering a balance of high current density and thermal resilience in standard through-hole packages.

Triacs Replacement Considerations

The MAC15MG is documented as an alternative part number within the same family, sharing similar physical dimensions and general functional characteristics for direct mechanical substitution.
