CDBER0230R-HF

Overview

The CDBER0230R-HF is a single silicon Schottky barrier rectifier diode manufactured by Comchip Technology. It features a surface-mount 0503 (SOD-723F) package designed for low-leakage applications. Key electrical parameters include a maximum repetitive reverse voltage of 30 V and an average forward current rating of 200 mA. The device exhibits a typical forward voltage drop of 600 mV at rated current and a maximum reverse leakage current of 1 uA. It supports a forward surge current of 1 A and operates within a junction temperature range up to 125°C.

Feature Summary

• Utilizes Schottky barrier technology to achieve low forward voltage drop and minimal power loss during conduction.
• Engineered for ultra-low reverse leakage current, enhancing efficiency in sensitive signal and power circuits.
• Constructed with silicon material for robust performance under standard operating conditions.

Applications

• Low-voltage DC-DC converter output rectification
• Power supply freewheeling diodes
• Signal detection and demodulation circuits

Procurement Notes

Verify the specific suffix 'HF' confirms halogen-free compliance when required by project specifications. Confirm the 0503/SOD-723F footprint matches the PCB design constraints. Ensure the 30 V reverse voltage rating provides adequate margin for the target circuit's peak inverse voltage. Cross-reference the datasheet for thermal derating curves if operating near the maximum junction temperature limit.

Selection Notes

Select this component for designs requiring a compact SMD solution with strict leakage current limits. The 200 mA current rating suits low-power applications where space is constrained. Compare the 600 mV forward voltage against alternative packages to ensure compatibility with system efficiency targets. Validate that the 1 A surge capability meets transient load requirements without exceeding absolute maximum ratings.

Part Context

This part belongs to Comchip Technology's series of small-signal Schottky diodes. It is specifically optimized for high-frequency switching applications due to its fast recovery characteristics. The 0503 package allows for automated assembly in dense consumer electronics layouts. It serves as a direct replacement for legacy components requiring similar electrical profiles in a smaller form factor.

Replacement Considerations

Check pinout compatibility with existing footprints before substitution. Verify that any alternative Schottky diode maintains the 30 V reverse voltage and 200 mA forward current ratings. Ensure the replacement package matches the 0503 dimensions to avoid mechanical interference.
