MA3D799

Diode Arrays Overview

The MA3D799 is a silicon epitaxial planar Schottky Barrier Diode (SBD) manufactured by Panasonic Electronic Components. It features a cathode-common dual configuration housed in a TO-220D-A1 package. The device supports an average forward current of 10 A and a repetitive peak reverse voltage of 30 V. Key electrical characteristics include a maximum forward voltage of 0.47 V at 5 A, a reverse leakage current of 3 mA at 30 V, and a junction-to-case thermal resistance of 3.0 °C/W. The component operates within a junction temperature range of -40 to +125 °C.

Diode Arrays Feature Summary

• Cathode-common dual structure for efficient switching applications
• Low forward voltage drop to minimize conduction losses
• High surge current capability for robust performance

Diode Arrays Applications

• Switching mode power supplies
• General electronic equipment rectification
• Office equipment power circuits

Diode Arrays Procurement Notes

Verify the specific lifecycle status directly with Panasonic or authorized distributors before procurement, as the datasheet indicates maintenance or discontinuation stages. Confirm that the TO-220D-A1 package dimensions match your PCB footprint requirements. Ensure compliance with RoHS Directive standards if required for your manufacturing process. Request the latest product standards from the manufacturer to confirm current specifications prior to final design implementation.

Diode Arrays Selection Notes

Select this component when a low-loss, high-current dual diode solution is required for power supply designs. The TO-220D-A1 package provides adequate thermal dissipation for 10 A continuous operation. Consider the 0.47 V forward voltage drop for efficiency calculations. Verify that the 30 V reverse voltage rating exceeds the peak inverse voltage in the target circuit. Evaluate the thermal resistance against the expected ambient operating conditions.

Diode Arrays Part Context

The MA3D799 belongs to Panasonic's series of silicon epitaxial planar Schottky Barrier Diodes designed for general-purpose rectification. It serves as a replacement for older models like the MA10799. The device is part of Panasonic's standard discrete semiconductor portfolio, focusing on reliability and efficiency for common industrial and consumer electronics applications.

Diode Arrays Replacement Considerations

The MA10799 is listed as a conventional equivalent part number for the MA3D799. Verify pinout compatibility and thermal characteristics when substituting.
