CS92D APM TIN/LEAD

Overview

The CS92D APM is a dual common cathode Schottky barrier rectifier manufactured by Central Semiconductor Corp. The device integrates two independent diodes within a single SOD-323 surface-mount package, designed for high-efficiency power conversion applications. Key electrical parameters include a maximum repetitive peak reverse voltage (VRRM) of 40 V and an average forward rectified current (IF(AV)) of 200 mA per diode. The component exhibits a low forward voltage drop of approximately 500 mV at a forward current of 100 mA, ensuring minimal power loss during conduction. It features a maximum DC reverse leakage current of 1 µA at the rated reverse voltage. The unit is rated for a junction temperature range from -65°C to +175°C, providing robust thermal performance for compact electronic designs.

Feature Summary

• Dual common cathode configuration allows for efficient bridge or full-wave rectification in space-constrained layouts.
• Schottky barrier technology ensures fast switching speeds and reduced reverse recovery time compared to standard PN junctions.
• Low forward voltage drop minimizes conduction losses and heat generation during operation.
• High thermal stability supports reliable performance across extended industrial temperature ranges.

Applications

• DC-DC converter output rectification
• Free-wheeling diodes in inductive load circuits
• Power supply input protection against reverse polarity

Procurement Notes

Verify the specific ordering suffix 'APM TIN/LEAD' to confirm the terminal finish composition, as lead-free alternatives may exist within the same product family. Confirm the package outline dimensions match the target PCB footprint prior to procurement. Ensure that the supplier provides traceability documentation consistent with the manufacturer's quality standards. Check for any recent lifecycle status updates regarding availability or obsolescence before finalizing purchase orders.

Selection Notes

Select this component when a low-voltage, low-current Schottky rectifier is required in an SOD-323 package. The 40 V rating suits low-voltage rail applications, while the 200 mA current capacity limits its use to small signal or auxiliary power stages. Consider the thermal resistance of the SOD-323 package for heat dissipation requirements. Evaluate the forward voltage characteristics against system efficiency targets. Compare alternative packages if higher current handling or different pin configurations are needed for the design.

Part Context

This part belongs to the Central Semiconductor Schottky diode portfolio, specifically designed for surface-mount assembly. The SOD-323 form factor is widely used in portable electronics and consumer devices where board space is limited. The dual common cathode arrangement simplifies circuit topology by reducing component count compared to using discrete single diodes. This series complements other low-power rectifiers offered by the manufacturer for comprehensive power management solutions.

Replacement Considerations

Direct replacements must match the SOD-323 package, 40 V reverse voltage, and 200 mA current rating. Verify that substitute parts maintain equivalent forward voltage and reverse leakage specifications. Ensure the replacement also offers a dual common cathode configuration to fit existing footprints without schematic changes. Cross-reference with manufacturers such as Diodes Incorporated or Vishay for comparable Schottky arrays.
