CDBQR40

Overview

The CDBQR40 is a single Schottky barrier rectifier from Comchip Technology, designed for surface mount applications. It features a 40V repetitive peak reverse voltage and a 200mA average forward rectified current. The device utilizes a leadless 0402/SOD-923F package to optimize board space. Key electrical characteristics include low reverse leakage current and majority carrier conduction for high efficiency.

Feature Summary

• Extremely thin and leadless package design suitable for small surface mounting
• Low reverse leakage current for improved performance
• Majority carrier conduction ensuring fast switching capabilities

Applications

• Surface mount circuits requiring minimal footprint
• Low voltage power supply rectification
• General purpose signal processing

Procurement Notes

Verify the specific suffix (e.g., -HF) against the manufacturer's datasheet to confirm RoHS compliance status. Ensure the ordering part number matches the required packaging configuration. Cross-reference the exact electrical parameters with the official Comchip Technology documentation before finalizing procurement specifications.

Selection Notes

Select this component for designs prioritizing ultra-low profile dimensions due to its 0402 form factor. It is appropriate for low-voltage, low-current applications where high-speed switching and minimal forward voltage drop are required. Consider thermal management requirements despite the small package size.

Part Context

This component belongs to the CDBQR series of SMD Schottky Barrier Diodes manufactured by Comchip Technology. The series is characterized by silicon epitaxial planar chips and metal-silicon junctions. It serves as a compact alternative to larger packages in portable and space-constrained electronic devices.

Replacement Considerations

The CDBQR40-HF is a documented variant within the same product line. Verify if the -HF suffix indicates specific environmental compliance or packaging differences compared to the base model before substitution.
