MAC4DCM-1G

Triacs Overview

The MAC4DCM-1G is a bidirectional triac manufactured by Littelfuse, designed for general-purpose power control applications. It features a non-repetitive peak on-state current of 40 A and a rated repetitive off-state voltage (VDRM) of 600 V. The device exhibits an on-state voltage of 1.6 V and a maximum holding current (Ih) of 35 mA. Gate triggering requirements include a maximum gate trigger voltage (Vgt) of 1.3 V and a maximum gate trigger current (Igt) of 35 mA. The component operates within a temperature range of -40°C to +125°C and is housed in a TO-251-3 through-hole package.

Triacs Feature Summary

• Logic-level sensitive gate architecture enabling direct interface with standard logic circuits.

Triacs Applications

• Lighting dimmer circuits
• Solid-state relays
• Motor speed control systems

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout configuration and packaging type. Ensure that the selected variant matches the required thermal management specifications for the intended application environment. Cross-reference the part number with Littelfuse documentation to validate RoHS compliance status and availability constraints before finalizing procurement orders.

Triacs Selection Notes

Select this component based on its 600 V blocking capability and 4 A RMS current rating for low-power AC switching tasks. The TO-251-3 package facilitates through-hole mounting, which may be preferred for specific mechanical stability requirements. Evaluate the 35 mA gate trigger current to ensure compatibility with the driving circuit's output capabilities without requiring additional amplification stages.

Triacs Part Context

This part belongs to the MAC4D series of triacs from Littelfuse, which are engineered for robust performance in consumer and industrial electronics. The MAC4DCM-1G specifically utilizes a sensitive gate design to simplify drive circuitry. It serves as a discrete semiconductor solution for controlling AC loads in compact form factors compared to larger leaded packages.

Triacs Replacement Considerations

The MAC4DLMT4G is a surface-mount alternative within the same family offering similar electrical characteristics but in a DPAK package. Verify pin compatibility and thermal dissipation differences when substituting between through-hole and SMD variants.
