MAC4DCNT4G

Triacs Overview

The MAC4DCNT4G is a bidirectional triac manufactured by Littelfuse, designed for AC power control applications. It features an 800 V rated repetitive off-state voltage (VDRM) and supports a non-repetitive peak on-state current of 40 A. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum holding current of 35 mA, a gate trigger voltage of 1.3 V, and a gate trigger current of 35 mA. It exhibits a low on-state voltage of 1.6 V and a leakage current of 10 µA at VDRM. Packaged in a DPAK-3 (TO-252-3) surface-mount format, it is supplied in reel, cut tape, or MouseReel configurations.

Triacs Feature Summary

• High voltage blocking capability suitable for demanding AC line applications
• Integrated thermal management via robust surface-mount package design
• Sensitive gate triggering characteristics for efficient driver interface

Triacs Applications

• Solid-state relay modules requiring high voltage isolation
• Industrial motor speed control circuits
• AC power switching systems with surge tolerance requirements

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm pinout compatibility and thermal specifications. Ensure that the procurement channel provides original Littelfuse documentation to validate RoHS compliance and traceability. Cross-reference the part number with official distributor catalogs to confirm availability status and lead times prior to finalizing supply chain commitments.

Triacs Selection Notes

Select this component when an 800 V rating is required for AC switching tasks. Compare the 35 mA gate trigger current against alternative devices if lower drive power is necessary. Evaluate the DPAK-3 package thermal resistance against the expected load current to determine if additional heatsinking is mandatory for reliable operation under continuous duty cycles.

Triacs Part Context

This device belongs to the MAC4DCN series of triacs from Littelfuse. It shares functional similarities with other members of the family but is distinguished by its specific 800 V voltage rating and associated thermal characteristics. The series is engineered for general-purpose AC control, offering a balance between high voltage handling and compact surface-mount integration for modern electronic designs.

Triacs Replacement Considerations

The MAC4DHM-1G is listed as an alias for this part number. Verify electrical equivalence before substitution. No other cross-model replacements are confirmed in public documentation.
