MAC4DCN-001

Triacs Overview

The MAC4DCN-001 is a silicon bidirectional thyristor (TRIAC) manufactured by onsemi, designed for industrial and consumer applications. It features an 800 V peak repetitive off-state voltage and a 4.0 A RMS on-state current rating at a case temperature of 108°C. The device operates within a junction temperature range of -40°C to 125°C and offers high immunity to dv/dt (500 V/µs at 125°C) and di/dt (6.0 A/ms at 125°C). Packaged in a DPAK-3 (CASE 369D), it includes passivated die technology for reliability and meets UL 94 V-0 epoxy standards.

Triacs Feature Summary

• Passivated die construction ensures device reliability and uniformity across production batches.
• High immunity to rate of change of commutating current (di/dt) and off-state voltage (dv/dt) enhances circuit robustness.
• Epoxy formulation complies with UL 94 V-0 flammability ratings for safety-critical environments.

Triacs Applications

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

Triacs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and shipping configuration. The MAC4DCN-001 designation corresponds to the standard rail packaging format. Confirm RoHS compliance status if required, as lead-free variants may carry distinct suffixes such as 'G'. Ensure compatibility with the intended thermal management strategy given the specified junction-to-case thermal resistance values.

Triacs Selection Notes

Select this component when an 800 V blocking capability and 4 A continuous current handling are required in a surface-mount form factor. Evaluate the thermal derating curves to ensure the RMS current rating remains sufficient under expected operating temperatures. Verify that the gate trigger characteristics align with the driving logic levels available in the target application circuit design.

Triacs Part Context

This part belongs to the MAC4DCM/MAC4DCN family of TRIACs from onsemi. The 'N' suffix specifically denotes the 800 V voltage rating variant, distinguishing it from the 600 V rated 'M' variant. Both share identical physical dimensions and electrical performance profiles except for the maximum blocking voltage specification.

Triacs Replacement Considerations

MAC4DCM-001 serves as a direct functional substitute within the same series, differing only in its lower 600 V voltage rating. Ensure the replacement voltage rating exceeds the peak line voltage present in the specific application circuit before implementation.

Triacs FAQ
