CDBQR0230L

Overview

The CDBQR0230L is a single silicon Schottky barrier diode manufactured by Comchip Technology. It features a surface-mount configuration in an extremely thin, leadless 0402 (SOD-923F) package. The device supports a maximum repetitive reverse voltage of 30 V and an average forward current of 200 mA. Key electrical parameters include a low forward voltage of 500 mV at 200 mA and a maximum reverse leakage current of 500 nA at 10 V. It operates with a junction temperature range up to 125 °C and is designed for high-efficiency rectification in compact electronic circuits.

Feature Summary

• Extremely thin and leadless package design optimized for small surface mounting
• Low forward voltage characteristic for improved power efficiency
• Majority carrier conduction mechanism ensuring fast switching performance

Applications

• Power ORing circuits requiring low voltage drop
• High-efficiency DC-DC converter output rectification
• Reverse polarity protection in portable devices

Procurement Notes

Verify the specific suffix designation when ordering, as variations such as -HF indicate halogen-free compliance. Confirm that the required reverse voltage rating aligns with the 30 V specification rather than higher variants like the 35 V rated CDBQR0230L. Ensure the 0402 footprint matches the target PCB layout constraints before finalizing procurement specifications.

Selection Notes

Select this component when board space is limited due to its SOD-923F form factor. It is appropriate for applications demanding low forward voltage drops to minimize power loss. Consider the 200 mA current limit for load requirements. Verify thermal management needs against the 125 °C junction temperature rating for reliable operation under varying environmental conditions.

Part Context

This part belongs to the CDBQR series of surface-mount Schottky diodes from Comchip Technology. It shares functional similarities with other low-profile packages like the CDBURT0230L but utilizes the distinct 0402/SOD-923F footprint. The series emphasizes miniaturization while maintaining standard Schottky characteristics for general-purpose rectification tasks.

Replacement Considerations

Direct substitutes include the CDBFR0230R, though it uses a larger 1005 package. For identical footprint replacement, verify compatibility with the CDBQR0230L-HF variant which offers halogen-free construction. Ensure any alternative maintains the 30 V reverse voltage and 200 mA forward current ratings.
