CDBER42

Overview

The CDBER42 is a silicon Schottky barrier rectifier manufactured by Comchip Technology. It features a single-phase, one-element configuration housed in an SOD-723F (0503) surface-mount package. The device supports a maximum repetitive reverse voltage of 30V and an average rectified forward current of 200mA. Designed for small-signal applications, it offers low forward voltage drop characteristics suitable for high-frequency switching circuits.

Feature Summary

• Utilizes silicon epitaxial planar chip technology for reliable performance
• Provides low forward voltage drop to minimize power loss
• Features fast switching capabilities with no reverse recovery time issues

Applications

• Polarity protection circuits
• Low voltage high frequency inverters
• Free wheeling diode applications

Procurement Notes

Verify the specific ordering suffix when sourcing components. Confirm that the received part matches the SOD-723F package dimensions and electrical ratings specified in the official datasheet. Ensure compliance with RoHS requirements if applicable to your assembly process.

Selection Notes

Select this component for designs requiring compact surface-mount solutions with moderate current handling. The 30V rating suits low-voltage DC systems. Consider thermal management requirements despite the small form factor, as junction temperature limits apply during operation.

Part Context

This device belongs to Comchip's line of small-signal Schottky diodes. It is designed for general-purpose rectification where speed and low forward voltage are critical. The SOD-723F package allows for automated placement in dense PCB layouts.

Replacement Considerations

Check pinout compatibility and voltage/current derating factors before substituting. Verify that alternative packages fit the existing footprint without modification.
