CDBF0240

Overview

The CDBF0240 is a silicon Schottky barrier diode manufactured by Comchip Technology, designed for surface-mount applications. It features a single configuration within the 1005 (2512 metric) package. The device supports an average forward current of 200 mA and a repetitive peak reverse voltage of 45 V. Key electrical characteristics include a maximum forward voltage of 450 mV and a reverse leakage current of 1 uA. It withstands a forward surge current of 3 A and dissipates up to 250 mW of power. The component operates at temperatures up to +125 C.

Feature Summary

• Utilizes majority carrier conduction for ultra-high-speed switching capabilities.
• Features an extremely thin, leadless molded plastic package optimized for small surface mounting.
• Provides guarding against overvoltage conditions with low forward voltage drop.

Applications

• Low profile surface mounted rectification in compact electronic designs.
• High-efficiency power conversion circuits requiring fast switching speeds.
• Overvoltage protection in sensitive signal paths.

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 1005 package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the 250 mW power dissipation limit under expected operating conditions. Cross-reference the datasheet version to confirm parameter consistency.

Selection Notes

Select this component when space constraints necessitate a low-profile SMD package like the 1005 format. Choose it for applications requiring fast recovery times due to its Schottky barrier construction. Consider the 200 mA current rating and 45 V reverse voltage limits to ensure adequate headroom for your circuit design. Evaluate the low forward voltage characteristic for efficiency gains in low-voltage systems.
