MAC4DSM-1G

Triacs Overview

The MAC4DSM-1G is a single TRIAC from Littelfuse, rated for 600V repetitive peak off-state voltage and 4A RMS on-state current. It utilizes a sensitive gate configuration to facilitate direct interfacing with microprocessor drivers. The component is housed in an IPAK (IN-LINE) package with three terminals and rectangular plastic/epoxy construction. It operates within a temperature range of -40°C to +125°C. The device complies with RoHS standards and connects electrically via Main Terminal 2.

Triacs Feature Summary

• Sensitive gate architecture designed for low-power triggering applications
• Robust IPAK through-hole packaging suitable for high-current inline mounting
• Compliant with environmental directives including RoHS

Triacs Applications

• Direct interface with microprocessor control circuits
• General purpose AC power switching
• Solid state relay implementations

Triacs Procurement Notes

Verify the specific manufacturer source, as Littelfuse and ON Semiconductor both list this part number. Confirm the package type matches the required PCB footprint, as datasheets may vary between manufacturers regarding exact mechanical dimensions and pinout orientation despite identical electrical ratings.

Triacs Selection Notes

Select this component when a 4A RMS current rating and 600V blocking capability are required in a through-hole IPAK package. Ensure the application circuit provides sufficient gate current to trigger the sensitive gate variant. Verify thermal management requirements for the operating environment, as the maximum junction temperature reaches 125°C.

Triacs Part Context

This part belongs to the MAC4D series of TRIACs, which are standardized for general-purpose AC control. The suffix 'SM' typically denotes the sensitive gate characteristic and the IPAK package style. It serves as a fundamental switching element in household appliances and industrial controllers requiring moderate power handling.

Triacs Replacement Considerations

MAC4DLMT4G is listed as an alias in distributor databases, though it utilizes a DPAK surface-mount package rather than the IPAK through-hole form factor. Direct substitution requires verifying package compatibility and ensuring the alternative maintains the 600V/4A rating.
