CDBQR0140L-HF

Overview

The CDBQR0140L-HF is a surface-mount Schottky barrier diode manufactured by Comchip Technology. It features a maximum repetitive peak reverse voltage (VRRM) of 40 volts and an average forward rectified current (Io) of 100 mA. The device utilizes majority carrier conduction to achieve low forward voltage characteristics. It is housed in an extremely thin, leadless package compatible with the 0402 or SOD-923F footprint, designed for efficient mounting on small surface areas.

Feature Summary

• Majority carrier conduction mechanism
• Low forward voltage drop
• Extremely thin leadless package design

Applications

• Surface mount assembly on compact circuit boards
• General purpose rectification in low-current applications
• Power supply input stages

Procurement Notes

Verify the specific datasheet version to confirm exact electrical limits and thermal resistance values. Ensure the ordering part number matches the required package style and tape/reel specifications. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement decisions.

Selection Notes

Select this component when space constraints require a leadless surface-mount package. It is suitable for applications demanding low forward voltage drops at currents up to 100 mA. Verify that the 40 V reverse voltage rating exceeds the maximum expected operating voltage in the target circuit design.

Part Context

This component belongs to Comchip Technology's series of surface-mount Schottky barrier diodes. These devices are engineered for high-efficiency rectification in portable and miniaturized electronics where board real estate is limited.

Replacement Considerations

Check for direct substitutes such as the CDBQR70-HF or CDBQR0130R-HF from the same manufacturer family. Ensure any replacement maintains identical voltage ratings, current capabilities, and physical package dimensions.
