CDBF54

Overview

The CDBF54 is a single Schottky barrier diode manufactured by Comchip Technology, designed for surface-mount applications. It features a maximum average forward rectified current of 200 mA and a maximum repetitive peak reverse voltage of 30 V. The device utilizes silicon technology and is housed in a compact 1005 (2512 metric) package. Key electrical characteristics include a maximum forward voltage of 1 V at the rated current and a low reverse leakage current of 2 uA. The component supports a maximum non-repetitive peak forward surge current of 600 mA and operates at temperatures up to +125 °C.

Feature Summary

• Schottky barrier construction for fast switching performance
• Silicon-based single diode configuration
• Compact surface-mount footprint

Applications

• General purpose rectification in low-current circuits
• Power supply input protection
• Signal demodulation applications

Procurement Notes

Verify the specific ordering suffix when sourcing this component. Manufacturers often use suffixes such as -HF to denote Halogen-free compliance or RoHS status. Ensure the purchased part matches the required environmental certifications for your assembly process. Confirm the package type corresponds to the 1005 metric designation during procurement to avoid mechanical fit issues on the PCB.

Selection Notes

Select the CDBF54 for designs requiring a small form factor with moderate current handling capabilities. The 30 V reverse voltage rating suits low-voltage DC systems. Consider the 1 V forward voltage drop when calculating power dissipation. The 200 mA current limit defines the maximum continuous load. Verify thermal management requirements based on the specified maximum operating temperature of +125 °C.

Part Context

This component belongs to the CDBF series of Schottky diodes from Comchip Technology. The series offers various voltage and current ratings within similar compact packages. The CDBF54 specifically targets applications needing 30 V blocking capability and 200 mA conduction. It serves as a discrete semiconductor solution for signal rectification and power management in consumer electronics and industrial control modules.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other 200 mA, 30 V Schottky diodes in the SOD-923F or equivalent 1005 package only after verifying pinout compatibility and electrical parameter margins.
