CS3P-40PB

Scrs Overview

The CS3P-40PB is a silicon planar epitaxial fast recovery rectifier manufactured by Central Semiconductor Corp. It features a three-terminal configuration with an integrated common cathode arrangement, designed for high-speed switching applications. The device provides a repetitive peak reverse voltage of 400V and supports a continuous forward current of 3A per terminal. Key electrical characteristics include a maximum average forward rectified current of 6A when operated in parallel configurations and a low forward voltage drop of 1.2V at rated conditions. The component utilizes a DO-201AD axial leaded package suitable for through-hole mounting.

Scrs Feature Summary

• Integrated common cathode structure enabling dual independent rectification within a single package
• Fast recovery time optimized for high-frequency power conversion circuits
• Planar epitaxial construction ensuring robust thermal stability and reliability

Scrs Applications

• High frequency DC to DC converter output rectification
• Free-wheeling diodes in switch-mode power supplies
• Reverse polarity protection in automotive electronics

Scrs Procurement Notes

Verify the manufacturer designation matches Central Semiconductor Corp exactly. Confirm the part number suffix indicates the standard DO-201AD axial package. Request the specific datasheet to validate the 400V rating and 3A current specifications against your circuit requirements before finalizing procurement.

Scrs Selection Notes

Select this component where space constraints favor a dual-diode solution over discrete parts. Ensure the operating frequency aligns with the fast recovery capabilities. Verify that the thermal management design accommodates the 6A total parallel current capability if both terminals are utilized simultaneously in the application.

Scrs Part Context

This component belongs to the family of fast recovery rectifiers produced by Central Semiconductor Corp. It serves as a specialized alternative to standard rectifiers requiring faster switching speeds. The three-terminal design distinguishes it from standard two-terminal diodes, offering compact integration for bridge-like functions or split-rail supplies.

Scrs Replacement Considerations

Consult official substitution lists for equivalent fast recovery rectifiers with matching 400V ratings and comparable recovery times. Verify pinout compatibility for the common cathode configuration before implementing any cross-reference components.
