MAC4DLM-001

Triacs Overview

The MAC4DLM-001 is a silicon bidirectional thyristor (Triac) manufactured by onsemi, designed for industrial and consumer applications. It features a DPAK-3 surface mount package with four-quadrant triggering capability. The device supports 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. Key electrical characteristics include a maximum on-state voltage of 1.6 V, a gate trigger current range up to 5.0 mA, and a holding current maximum of 15 mA. The component operates within a junction temperature range of -40°C to 110°C and offers ESD protection ratings of 8000 V via the Human Body Model.

Triacs Feature Summary

• Four-quadrant triggering ensures reliable operation across all gate and main terminal polarities.
• Passivated die construction provides enhanced reliability and uniformity for high-volume production.
• Epoxy material meets UL 94 V-0 flammability standards for safety compliance.
• Low-level triggering and holding characteristics facilitate efficient drive circuit design.

Triacs Applications

• Motor control systems
• Process control equipment
• Temperature regulation circuits
• Light dimming applications
• Speed control mechanisms

Triacs Procurement Notes

Verify the specific ordering suffix when sourcing components. The base part number MAC4DLM corresponds to the standard version, while the -001 suffix indicates rail packaging containing 75 units per rail. Ensure compatibility with required lead-free specifications if applicable, as separate Pb-free variants exist under different suffixes such as G or T4. Confirm package style matches the design footprint requirements before procurement.

Triacs Selection Notes

Select this component for applications requiring robust AC switching in compact surface-mount designs. Evaluate thermal management needs based on the 4.0 A RMS rating at 93°C case temperature. Consider the low gate trigger current for compatibility with sensitive microcontroller outputs. Verify that the 600 V blocking voltage exceeds the peak line voltage plus transient spikes in the target circuit environment.

Triacs Part Context

This Triac belongs to the MAC4DLM family of sensitive gate thyristors from onsemi. These devices are engineered for cost-effective solutions in mass-produced electronics. The DPAK-3 package allows for automated assembly processes. The product line targets general-purpose AC power control tasks where small form factor and adequate current handling are primary design constraints.

Triacs Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official replacement guides or contact manufacturer technical support for validated cross-reference data. Do not assume pin-compatible alternatives without verifying electrical parameters and thermal characteristics against the original specification sheet.
