CDBF0240-HF

Overview

The CDBF0240-HF is a silicon Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration in an SMD/SMT package, specifically the 1005 (2512 metric) case style. The device supports a forward current of 200 mA and a repetitive reverse voltage of 45 V. Key electrical parameters include a maximum forward voltage of 450 mV, a reverse current of 1 uA, and a forward surge current of 3 A. Power dissipation is rated at 250 mW, with an operating temperature range up to +125 C.

Feature Summary

• Majority carrier conduction for ultra-high-speed switching capabilities
• Extremely thin and leadless package design optimized for small surface mounting
• Low forward voltage drop characteristics to minimize power loss

Applications

• High-frequency rectification in compact electronic circuits
• Power supply input protection stages
• Reverse polarity protection in low-current signal paths

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure compliance with relevant environmental standards such as RoHS requirements before integration into final assemblies. Cross-reference datasheet revisions to validate parameter consistency.

Selection Notes

Select this component for applications requiring low-profile surface mount solutions with high switching speeds. The 200 mA current rating suits low-power signal processing or protection tasks. Evaluate thermal management needs relative to the 250 mW power dissipation limit within the constrained 1005 package footprint.

Part Context

This part belongs to the Comchip Technology CDBF series of Schottky barrier diodes. These devices utilize silicon epitaxial planar chip technology with metal-silicon junctions. The series is designed to offer superior reverse leakage current performance and thermal resistance compared to standard alternatives.

Replacement Considerations

Direct substitutes may include other 200 mA, 40-45 V Schottky diodes in compatible 1005 or SOD-323F packages. Verify pinout compatibility and forward voltage specifications when considering alternative manufacturers.
