CDBER54-HF

Overview

The CDBER54-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a single diode configuration in an SOD-723F (0503) package. Key electrical specifications include a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current of 200 mA. The device utilizes silicon epitaxial planar chip technology with a metal-silicon junction to ensure ultra-high-speed switching capabilities.

Feature Summary

Ultra-high-speed switching performance suitable for high-frequency circuits
Low forward voltage drop for improved power efficiency
Guardring structure provides enhanced overvoltage protection stability

Applications

High-frequency rectification in consumer electronics
DC-DC converter output stages
Polarity protection circuits

Procurement Notes

Verify the specific suffix 'HF' indicates Halogen-Free compliance as per manufacturer standards. Confirm the package designation matches SOD-723F or 0503 dimensions for PCB footprint compatibility. Ensure RoHS directive adherence requirements are met for the target assembly process. Cross-reference datasheet revision dates to confirm parameter consistency.

Selection Notes

Select this component when low capacitance and fast recovery are prioritized over high current handling. The 200 mA rating limits suitability for high-power applications; verify thermal management needs for continuous operation. Compare leakage current specifications against sensitive input circuit requirements. Ensure the 30 V reverse voltage margin accommodates peak line transients.

Part Context

This part belongs to Comchip's CDBE series of small-signal Schottky rectifiers. It complements higher-current SMA/SMB packages like the CDBA520-HF by offering a compact solution for low-power signal paths. The SOD-723F form factor allows for dense board layouts in portable devices where space is constrained compared to larger DO-214AC variants.
