DB4-AP

Overview

The MCC DB4-AP is a single-phase bridge rectifier manufactured by Micro Commercial Components. It utilizes glass passivated junction technology for enhanced reliability and stability under varying thermal conditions. The device is designed for general-purpose AC-to-DC conversion applications requiring robust performance in compact form factors. Key electrical specifications include a maximum repetitive peak reverse voltage of 400V and an average forward rectified current rating of 1A. The component features a low forward voltage drop to minimize power loss and heat generation during operation. It is housed in a DO-201AD (DO-15) axial leaded package, suitable for through-hole mounting on printed circuit boards.

Feature Summary

• Glass passivated junction construction ensures high reliability and stable performance across temperature variations.
• High surge current capability provides protection against transient overloads during initial power-up or fault conditions.
• Low forward voltage drop design contributes to improved efficiency and reduced thermal stress in the circuit.

Applications

• General-purpose AC to DC power supply circuits
• Battery charging systems
• Adapters and power bricks

Procurement Notes

Verify the specific datasheet version for the DB4-AP part number before procurement, as manufacturing updates may occur. Confirm that the DO-201AD package dimensions match your PCB footprint requirements. Ensure that the 400V reverse voltage rating meets the peak inverse voltage demands of your specific AC input line. Check for RoHS compliance status if required by your assembly regulations. Contact the manufacturer or authorized distributors for current availability and lead times, as this component may have limited stock.

Selection Notes

Select the DB4-AP when a 1A current rating and 400V reverse voltage are sufficient for the application. Consider this component for through-hole designs where axial leads offer mechanical stability. Compare the forward voltage characteristics with other bridge rectifiers if thermal management is critical. Ensure the operating temperature range aligns with the environmental conditions of the final product. Evaluate the physical size constraints of the DO-201AD package against available board space.

Part Context

The DB4-AP belongs to the family of single-phase bridge rectifiers produced by Micro Commercial Components. These components are widely used in consumer electronics and industrial control systems for rectifying alternating current. The DB series typically offers a range of voltage ratings to suit different input requirements. This specific model represents a standard solution for low-power AC conversion tasks.

Replacement Considerations

Equivalent parts from other manufacturers include the MB4 series or similar 1A/400V bridge rectifiers in the DO-201AD package. Verify pinout compatibility and electrical parameters such as forward voltage and leakage current before substitution. Ensure the replacement component meets the same safety and regulatory standards required by the original design.
