Diode Arrays Procurement Notes

Verify the specific lifecycle status on the manufacturer's official website before procurement, as this component may be subject to maintenance or discontinuation plans. Confirm that the required specifications align with standard application guidelines rather than special safety-critical environments. Ensure compliance with RoHS directives and handle the device with electrostatic discharge precautions during assembly.

Diode Arrays Selection Notes

Select the MA3D752A when a robust Schottky rectifier with a 45 V reverse voltage capability and 20 A average current handling is required. The TO-220D-A1 package facilitates through-hole mounting with V-cut leads for ease of installation. Consider the thermal resistance and junction temperature limits to ensure adequate heat dissipation in the target power supply design.

Diode Arrays Part Context

This component belongs to the MA3D752 series of silicon epitaxial planar Schottky barrier diodes manufactured by Panasonic Electronic Components. The series includes variants such as the MA3D752 and MA7D52, sharing similar structural characteristics but differing in specific electrical ratings like reverse voltage. These devices are engineered for general electronic equipment and standard applications.

Diode Arrays Replacement Considerations

Consult the manufacturer's official documentation for confirmed substitute part numbers. Cross-reference electrical parameters such as reverse voltage, forward current, and package dimensions to ensure compatibility.
