Triacs datasheet and documents for MAC4DHM-1G
Triacs Overview
The MAC4DHM-1G is a surface-mount bidirectional thyristor (TRIAC) manufactured by Littelfuse. It features a DPAK-3 package with four-quadrant triggering and a peak repetitive off-state voltage of 600 V. The device supports an on-state RMS current of 4.0 A at a case temperature of 93°C and can withstand a peak non-repetitive surge current of 40 A. Electrical characteristics include a maximum on-state voltage of 1.6 V, a holding current of up to 15 mA, and a gate trigger voltage of 1.3 V. Operating junction temperatures range from -40°C to +110°C.
Triacs Feature Summary

Triacs Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping quantity. The '-1G' designation indicates a lead-free package variant within the MAC4DHM series. Confirm availability status as distribution channels may vary. Ensure the component matches the required thermal resistance and current derating curves for the target application environment.
Triacs Selection Notes
Select this component based on the 600 V blocking voltage and 4.0 A RMS current rating relative to the load requirements. Evaluate the thermal management needs using the specified junction-to-case thermal resistance of 3.5 °C/W. Consider the low gate trigger current for compatibility with driving circuitry. Verify that the DPAK-3 footprint aligns with the PCB layout constraints and soldering profile capabilities.
Triacs Part Context
The MAC4DHM-1G belongs to the MAC4DHM family of surface-mount thyristors designed for industrial and consumer electronics. This series emphasizes compact packaging and cost-effective manufacturing for high-volume production. The device utilizes a passivated die to ensure parameter stability over its operational lifetime.
Triacs Replacement Considerations
The MAC4DCNT4G is documented as an alternative part number within the same product ecosystem. Verify electrical specifications such as voltage ratings and current handling before substitution.
