CDBER40

Overview

The CDBER40 is a small signal Schottky barrier rectifier manufactured by Comchip Technology. It features a single silicon element with a maximum average forward rectified current of 200mA and a maximum repetitive peak reverse voltage of 40V. The device utilizes a surface-mount 0503/SOD-723F package, designed for low-profile applications to optimize board space. Key electrical characteristics include a low forward voltage drop and high surge capability, ensuring efficient power conversion in compact electronic designs.

Feature Summary

• Ultra-high-speed switching capability for efficient signal rectification
• Low profile surface mount package optimized for board space conservation
• Guarding against overvoltage protection scenarios
• Lead-free construction compliant with environmental standards

Applications

• Low profile surface mounted applications requiring board space optimization
• Overvoltage protection circuits
• Small signal rectification in compact electronic devices

Procurement Notes

Verify the specific ordering suffix when sourcing components. Confirm that the requested part matches the exact voltage and current ratings required for the design. Ensure compatibility with the specified SOD-723F footprint during PCB layout validation. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Selection Notes

Select this component for designs prioritizing minimal physical footprint alongside reliable Schottky performance. The 200mA current rating suits low-power signal paths rather than high-current power stages. Consider the 40V reverse voltage limit when designing circuits with potential transient spikes exceeding this threshold. The SOD-723F package requires appropriate solder paste stencils for reliable reflow attachment.

Part Context

This device belongs to the Comchip Technology Schottky diode family, specifically engineered for surface mount technology. It shares design principles with other low-profile rectifiers in the series, emphasizing thermal resistance and reverse leakage current management. The component serves as a discrete semiconductor solution for modern miniaturized electronics where traditional through-hole packages are impractical.

Replacement Considerations

Cross-reference with CDBER40-HF for identical specifications with explicit halogen-free certification. Verify pinout compatibility with existing footprints before substituting alternative manufacturers' equivalents.
