CDBC320-HF

Overview

The CDBC320-HF is a surface-mount Schottky barrier rectifier manufactured by Comchip Technology in the DO-214AB (SMC) package. It features a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current of 3 A. The device exhibits a maximum DC reverse leakage current of 500 µA at 20 V and a junction capacitance of 380 pF at 4 V and 1 MHz. It is designed for low power loss, high efficiency, and high current capability with a low forward voltage drop.

Feature Summary

• Schottky barrier technology for fast switching and low forward voltage
• Low profile surface mount design to optimize board space
• High current capability with low power loss and high efficiency

Applications

• Telecommunications equipment
• Industrial power supplies
• Automotive electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the part number with authorized distributors to validate authenticity and availability status before finalizing procurement decisions.

Selection Notes

Select this component when a 20 V reverse voltage rating and 3 A continuous forward current are required in a compact SMC footprint. Consider its Schottky characteristics for applications prioritizing low forward voltage drop and fast recovery times over higher voltage blocking capabilities. Ensure thermal management aligns with the DO-214AB package limitations.

Part Context

This part belongs to the CDBC series of single Schottky barrier rectifiers from Comchip Technology. The series includes variants with different current ratings and voltage specifications, all sharing the DO-214AB surface-mount package. These devices are engineered for general-purpose rectification in space-constrained electronic designs requiring reliable performance.

Replacement Considerations

Direct substitutes include other 20V 3A Schottky diodes in the DO-214AB package, such as those from Vishay or ON Semiconductor. Verify pinout compatibility and thermal resistance parameters before substitution. Alternative parts must match the 20 V reverse voltage and 3 A forward current specifications.
