CDBFR0240-HF

Overview

The CDBFR0240-HF is a silicon Schottky barrier rectifier manufactured by Comchip Technology. It features a single diode configuration housed in a compact 1005 (SOD-323F) surface-mount package. The device supports a maximum average forward current of 200 mA and a repetitive peak reverse voltage of 40 V. Key electrical characteristics include a low forward voltage drop of 450 mV at rated current, a maximum reverse leakage current of 1 uA, and a non-repetitive peak forward surge current capability of 3 A. The component is designed for operation within a junction temperature range up to +125 °C with a power dissipation rating of 250 mW.

Feature Summary

• Utilizes majority carrier conduction for fast switching performance and reduced recovery time.
• Features an extremely thin, leadless molded plastic package optimized for small surface mounting.
• Constructed with gold-plated terminals that are solderable per MIL-STD-750 standards.

Applications

• High-frequency rectification in compact consumer electronics.
• Power supply circuits requiring low forward voltage drop.
• DC-DC converter input or output stages.

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure compliance with RoHS directives and check for halogen-free status if required by project specifications. Confirm the package type matches the intended PCB footprint design before finalizing procurement orders.

Selection Notes

Select this component when space constraints necessitate a 1005 SMD form factor while maintaining reliable 200 mA current handling. The low forward voltage characteristic makes it suitable for low-voltage applications where efficiency is critical. Verify thermal management requirements align with the 250 mW power dissipation limit under expected operating conditions.
