CDBFR0140L

Overview

The CDBFR0140L is a surface-mount Schottky Barrier Diode manufactured by Comchip Technology. It features an average forward rectified current (Io) of 100 mA and a repetitive peak reverse voltage (VRRM) of 40 Volts. The device utilizes a leadless 1005/SOD-323F package, designed for compact circuit layouts. Key electrical characteristics include low forward voltage drop and low reverse leakage current, ensuring high efficiency in signal processing applications.

Feature Summary

• Extremely thin and leadless package design suitable for space-constrained surface mounting
• Majority carrier conduction providing fast switching capabilities
• Low forward voltage drop for improved power efficiency
• Low reverse leakage current to minimize standby power loss

Applications

• High-frequency signal detection circuits
• Power supply rectification in portable devices
• Clamping and protection diodes in small form-factor electronics

Procurement Notes

Verify the specific suffix (e.g., -HF) against the required environmental compliance standards, as standard listings may vary. Confirm the package type matches the PCB footprint requirements, specifically the 1005/SOD-323F dimensions. Ensure the operating temperature range aligns with the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, leadless Schottky diode is required for high-speed switching or low-voltage rectification. The 100 mA current rating suits low-power signal applications rather than high-current power conversion. Consider the 40 V reverse voltage limit to ensure adequate margin against transient spikes in the target circuit design.

Part Context

This part belongs to Comchip Technology's SMD Schottky Barrier Diode series, which emphasizes miniaturization through leadless packaging. The CDBFR0140L specifically targets applications requiring reliable performance in minimal footprints, leveraging silicon epitaxial planar chip technology for consistent thermal and electrical stability.

Replacement Considerations

Check for equivalent parts from other manufacturers offering identical 100 mA/40 V ratings in SOD-323F packages. Verify pinout compatibility and forward voltage specifications to ensure seamless integration without redesigning the surrounding circuitry.
