CDBF0130

Overview

The CDBF0130 is a Schottky barrier rectifier manufactured by Comchip Technology. It features an average forward current (Io) of 100mA and a maximum DC reverse voltage (Vr) of 30V. The device utilizes a surface mount installation type in a 0402 (1006 metric) package, also identified as SOD-923F. The junction temperature rating reaches a maximum of 125°C. Forward voltage is specified at 450mV when tested at 10mA. Reverse leakage current is limited to 500nA at 10V. The component operates within the small signal speed category for currents up to 200mA.

Feature Summary

• Utilizes silicon epitaxial planar chip technology with metal-silicon junction construction.
• Features majority carrier conduction for ultra-high-speed switching capabilities.
• Designed with an extremely thin leadless package optimized for small surface mounting.

Applications

• Low profile surface mounted applications requiring board space optimization.
• Overvoltage protection circuits utilizing high surge capability.
• Power supply rectification where low forward voltage drop is required.

Procurement Notes

Verify the specific suffix designation on the datasheet, as variants such as CDBF0130R or CDBF0130L-HF may exist with distinct packaging or electrical tolerances. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the ordering part number matches the exact package style required for the PCB footprint to avoid mechanical integration errors during procurement.

Selection Notes

Select this component for designs prioritizing minimal physical footprint due to the 0402/SOD-923F package dimensions. The 30V reverse voltage rating suits low-voltage DC-DC converter outputs. Consider the 100mA average current limit when sizing for load requirements. The low forward voltage characteristic aids in improving overall system efficiency compared to standard PN junction diodes in similar form factors.

Part Context

This device belongs to the Comchip Technology SMD Schottky Barrier Diode family. It shares functional similarities with other low-current surface mount rectifiers designed for portable electronics. The product line emphasizes batch process design for consistent thermal resistance and reverse leakage performance across manufacturing lots.

Replacement Considerations

The CDBQC0130L-HF is listed as a manufacturer-recommended substitute. Verify pinout compatibility and ensure the replacement maintains the required 30V reverse voltage and 100mA current ratings for the specific application circuit.
