MAC4DCN-1G

Triacs Overview

The MAC4DCN-1G is a standard triac manufactured by Littelfuse, belonging to the MAC4D series. It features an 800 V rated repetitive off-state voltage and supports a 4 A RMS on-state current. The device operates within a junction temperature range of -40°C to +125°C. Key electrical parameters include a maximum gate trigger voltage of 1.3 V and a gate trigger current of 35 mA. It utilizes a DPAK-3 (TO-252-3) surface-mount package.

Triacs Feature Summary

• Integrated glass-passivated junctions for long-term parameter stability
• Designed for AC switching and phase control applications
• Suitable for noise-immune environments

Triacs Applications

• AC speed controls
• Temperature modulation controls
• Lighting controls

Triacs Procurement Notes

Verify the manufacturer designation carefully, as this component type has been produced by multiple entities including onsemi and Motorola. Confirm the specific datasheet version matches the required electrical tolerances. Ensure the ordering suffix aligns with the desired packaging format, such as cut tape or reel, before finalizing procurement orders.

Triacs Selection Notes

Select this component when an 800 V blocking capability is required alongside a 4 A continuous current rating in a compact surface-mount form factor. Verify that the gate drive circuit can supply at least 35 mA to ensure reliable triggering under all operating conditions. Consider thermal management requirements given the DPAK-3 package constraints.

Triacs Part Context

This part belongs to the MAC4D family of standard triacs. Variants within this series differ primarily in voltage ratings, such as the 600 V rated MAC4DLMT4G. The MAC4DCN-1G specifically denotes the 800 V variant in the DPAK-3 package configuration.

Triacs Replacement Considerations

Publicly documented equivalent part numbers include MAC4DCNT4G and MAC4DCN T4G. These variants share identical electrical specifications and pinout configurations, allowing for direct substitution in existing designs.
