MAC15A8G

Triacs Overview

The MAC15A8G is a bidirectional triac manufactured by Littelfuse, designed for AC power control applications. It features a TO-220-3 through-hole package with three pins. The device has a rated repetitive off-state voltage (VDRM) of 600 V and an on-state voltage of 1.6 V. Non-repetitive peak on-state current is rated at 150 A. The maximum holding current (Ih) is 40 mA, while the gate trigger voltage (Vgt) is 2.5 V and gate trigger current (Igt) is 75 mA. Operating temperature range spans from -40 C to +125 C.

Triacs Feature Summary

• Bidirectional switching capability for AC phase control
• Glass-passivated junctions for parameter stability
• Through-hole mounting in a TO-220-3 package

Triacs Applications

• AC motor speed controls
• Lighting dimmer circuits
• Temperature modulation systems

Triacs Procurement Notes

Verify component authenticity against Littelfuse official documentation before integration. Confirm that the specific suffix 'G' aligns with required environmental compliance standards such as RoHS. Ensure thermal management design accommodates the specified operating temperature limits during high-current operation.

Triacs Selection Notes

Select this component when a 600 V blocking voltage and 15 A RMS current rating are required in a standard TO-220 package. Compare gate trigger characteristics against driver capabilities, as the 75 mA Igt requirement may necessitate specific drive circuitry. Evaluate thermal resistance requirements based on the expected duty cycle and ambient conditions.

Triacs Part Context

This part belongs to the MAC15A series of triacs from Littelfuse. It shares similar electrical characteristics with other variants in the family but differs primarily in its voltage rating. The MAC15A8G specifically targets applications requiring 600 V isolation, distinguishing it from lower or higher voltage siblings within the same current-rated product line.

Triacs Replacement Considerations

MAC15MG is listed as an alias for this part number. Verify pinout compatibility and exact electrical tolerances if substituting with other 600 V, 15 A triacs from different manufacturers.
