CDBFR0145

Overview

The CDBFR0145 is a Schottky Barrier Rectifier manufactured by Comchip Technology. It features a maximum average forward rectified current of 100 mA and a maximum repetitive peak reverse voltage of 45 V. The device utilizes silicon epitaxial planar chip technology with a metal-silicon junction, ensuring majority carrier conduction for ultra-high-speed switching. Designed for surface mount applications, it offers low forward voltage drop and high surge capability while maintaining compliance with environmental standards.

Feature Summary

• Low profile package design suitable for space-constrained surface mount applications
• Majority carrier conduction enabling ultra-high-speed switching performance
• Guarding functionality for overvoltage protection scenarios

Applications

• General purpose rectification in compact electronic circuits
• Overvoltage protection in low-current signal paths
• High-frequency switching applications requiring fast recovery

Procurement Notes

Verify the specific suffix designation against official documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with RoHS and MIL-STD-19500/228 environmental standards required for your assembly process. Cross-reference the datasheet for precise thermal resistance values and maximum operating temperature limits before finalizing component selection.

Selection Notes

Select this component when a low-profile Schottky diode is required for small surface-mount footprints. Consider its 100 mA current rating and 45 V reverse voltage capabilities for low-power rectification tasks. Evaluate the trade-off between its compact form factor and current handling capacity compared to standard packages like SOD-123.

Part Context

This part belongs to the CDBFR series of Schottky Barrier Diodes from Comchip Technology. These devices are characterized by their extremely thin, leadless package designs intended for automated surface mounting. The series emphasizes high efficiency and low power loss through optimized silicon epitaxial planar chip structures.

Replacement Considerations

Consult official substitution lists for verified equivalents. Generic replacements must match the 100 mA forward current, 45 V reverse voltage, and compatible surface mount package dimensions to ensure functional parity without redesign.
