MAC4DLM-1G

Triacs Overview

The MAC4DLM-1G is a surface-mount bidirectional thyristor (triac) from Littelfuse, housed in a DPAK-3 package. It features a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 4.0 A at a case temperature of 93°C. The device supports a peak non-repetitive surge current of 40 A and operates within a junction temperature range of -40°C to +110°C. Electrical characteristics include a maximum on-state voltage of 1.6 V at ±6.0 A, a holding current maximum of 15 mA, and gate trigger currents ranging from 1.8 mA to 5.0 mA depending on the quadrant. Thermal resistance from junction to case is 3.5 °C/W.

Triacs Feature Summary

Triacs Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the presence of the 'G' suffix indicates lead-free packaging compliance. Ensure ordering quantities align with standard shipping configurations such as tape and reel or box units. Validate that the specific variant matches the required thermal and electrical ratings for the intended circuit design before finalizing procurement.

Triacs Selection Notes

Select this component when a compact surface-mount solution is required for low-to-medium power AC switching tasks. The DPAK-3 package offers space efficiency compared to through-hole alternatives while maintaining adequate thermal performance for industrial environments. Consider the 600V blocking voltage and 4A current rating to ensure sufficient margin for the specific load conditions and transient events expected in the application.

Triacs Part Context

This part belongs to the MAC4DLM series of surface-mount thyristors manufactured by Littelfuse. The series is engineered for high-volume production in consumer and industrial electronics. The MAC4DLM-1G specifically denotes the lead-free version of the standard MAC4DLM device, adhering to environmental regulations while providing identical electrical and mechanical performance characteristics.

Triacs Replacement Considerations

The MAC4DLMT4G is a verified alternative within the same series, offering identical electrical specifications in a tape and reel package configuration.
