CDBF0230R-HF

Overview

The CDBF0230R-HF is a silicon Schottky barrier rectifier manufactured by Comchip Technology, designed for high-speed switching and low-loss rectification. It features a single diode configuration in a compact 1005 (2512 metric) surface-mount package. Key electrical parameters include a maximum repetitive reverse voltage (Vrrm) of 30 V and an average forward rectified current (If) of 200 mA. The device exhibits a typical forward voltage drop (Vf) of 600 mV at the rated current and a low reverse leakage current (Ir) of 1 µA. It supports a forward surge current (Ifsm) of 1 A and operates within a junction temperature range up to 150°C.

Feature Summary

• Utilizes silicon Schottky technology for fast recovery times and minimal power loss during switching operations.
• Engineered with a low-profile 1005 surface-mount footprint to facilitate automated assembly and space-constrained PCB layouts.
• Provides stable rectification performance with controlled forward voltage characteristics suitable for low-voltage DC circuits.

Applications

• High-frequency DC-DC converter output rectification
• Power supply freewheeling diodes in portable electronics
• Reverse polarity protection in low-voltage battery-powered devices

Procurement Notes

Verify the specific suffix 'HF' confirms halogen-free compliance as per manufacturer specifications. Confirm the package designation matches the 1005 (2512 metric) SMD form factor required for your board design. Ensure the voltage and current ratings align with your circuit's peak operating conditions to maintain reliability under thermal stress.

Selection Notes

Select this component when a small signal Schottky diode is required for efficient rectification in tight spaces. The 30 V rating suits low-voltage applications, while the 200 mA current capacity supports moderate load requirements. Compare against similar series parts if higher current or voltage ratings are needed for future scalability.

Part Context

This part belongs to the CDBF series of Schottky diodes from Comchip Technology, which focuses on compact, high-reliability rectifiers for consumer and industrial electronics. The series emphasizes low forward voltage and fast switching speeds, making it suitable for modern power management ICs and synchronous rectification alternatives in cost-sensitive designs.

Replacement Considerations

Direct substitutes may include other 30V 200mA Schottky diodes in the 1005 package, such as the CDBU0230R-HF if pinout compatibility allows, or generic equivalents like BAS40 variants if package dimensions differ. Verify thermal resistance and reverse leakage specifications match original requirements.
