MA3D750

Diode Arrays Overview

The Panasonic MA3D750 is a silicon epitaxial planar Schottky Barrier Diode (SBD) with a common cathode configuration, designed for switching mode power supplies. It operates within a junction temperature range of -40°C to +125°C and utilizes a TO-220D-A1 package. The device features a repetitive peak reverse voltage rating of 40V and an average forward current capacity of 10A. Key electrical characteristics include a maximum forward voltage of 0.55V at 5A and a thermal resistance from junction to case of 3.0°C/W.

Diode Arrays Feature Summary

• Low forward voltage drop for improved efficiency
• High dielectric breakdown voltage exceeding 5 kV
• Common cathode dual diode configuration
• V-cut lead ends for simplified mounting

Diode Arrays Applications

• Switching mode power supplies
• General electronic equipment
• Office equipment
• Communications equipment

Diode Arrays Procurement Notes

Verify the specific lifecycle status before procurement, as this component may be classified under maintenance or discontinued plans. Confirm that the selected variant matches the required reverse voltage rating, as the MA3D750A offers a higher rating than the standard MA3D750. Ensure compliance with RoHS directives and validate that the application falls within standard general electronics usage rather than specialized safety-critical systems.

Diode Arrays Selection Notes

Select the MA3D750 for applications requiring low forward voltage and high surge current handling up to 120A. Consider the MA3D750A if a higher repetitive peak reverse voltage of 45V is necessary. Evaluate the thermal management requirements based on the 3.0°C/W junction-to-case thermal resistance. Ensure the design accommodates the TO-220D-A1 package dimensions and V-cut lead specifications for proper mechanical mounting.

Diode Arrays Part Context

This component belongs to the Panasonic Schottky Barrier Diode family, specifically engineered for silicon epitaxial planar technology. It serves as a robust rectification solution in power conversion circuits. The product line includes variants like the MA3D750A, which provides adjusted voltage ratings while maintaining similar current capabilities and physical form factors for interchangeable design integration.

Diode Arrays Replacement Considerations

Consult official documentation for confirmed substitute part numbers. Verify compatibility regarding package type, pinout configuration, and absolute maximum ratings when considering alternative components.
