CDBUR0240-HF

Single Diodes Overview

The CDBUR0240-HF is a single silicon Schottky barrier diode manufactured by Comchip Technology. It features a surface-mount DFN package, specifically the 0603 (1608 metric) or SOD-523F form factor. The device supports a maximum average forward rectified current of 200 mA and a repetitive peak reverse voltage of 45 V. Key electrical characteristics include a low forward voltage drop of 0.55 V maximum at rated current and a very low reverse leakage current of 1 uA. It withstands a non-repetitive peak forward surge current of 2 A and operates at junction temperatures up to +125 °C.

Single Diodes Feature Summary

• Utilizes majority carrier conduction for fast switching performance
• Features an extremely thin, leadless DFN package designed for small surface mounting
• Constructed with silicon technology for reliable operation

Single Diodes Applications

• Portable consumer electronics requiring compact power management
• DC-DC converter circuits in space-constrained designs
• Low-voltage rectification in battery-powered devices

Single Diodes Procurement Notes

Verify the specific suffix against official datasheets to confirm RoHS compliance and halogen-free status. Confirm the exact package dimensions match the design footprint, as variations exist within the series. Ensure the ordering code aligns with the required tape-and-reel quantity specifications provided by the manufacturer.

Single Diodes Selection Notes

Select this component when a low-profile surface-mount solution is required for small-signal rectification. The 0603 package offers a balance between current handling capability and board space efficiency. Consider the thermal dissipation limits and ensure the application does not exceed the maximum operating temperature of 125 °C under continuous load conditions.

Single Diodes Part Context

This part belongs to the CDBUR series of small-signal Schottky diodes from Comchip Technology. The series is characterized by its use of standard DFN/flat chip packages that comply with RoHS directives. These components are engineered for high reliability and zero tin whisker generation, making them suitable for sensitive electronic assemblies where space is limited.

Single Diodes Replacement Considerations

Direct substitutes must match the 200 mA current rating, 40V/45V voltage rating, and 0603/SOD-523F package. Verify that alternative Schottky diodes maintain comparable forward voltage and leakage current specifications to ensure circuit performance parity.
