CDBFN160-HF

Overview

The CDBFN160-HF is a low-profile Schottky barrier rectifier from Comchip Technology, housed in an SOD-323 package. It features a silicon epitaxial planar chip with a metal-silicon junction. Key electrical parameters include a repetitive reverse voltage (Vrrm) of 60 V and a forward current (If) of 1 A. The forward voltage drop (Vf) is typically 550 mV, with a maximum reverse leakage current (Ir) of 500 uA. The device supports a forward surge current (Ifsm) of 30 A and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Ultra-high-speed switching capability for efficient power conversion
• Low profile package design optimized for surface mount board space
• Guarding against overvoltage conditions through robust surge handling
• Lead-free construction compliant with environmental standards

Applications

• Low voltage rectification in compact electronic circuits
• High-frequency switching power supplies
• Reverse polarity protection in sensitive electronics

Procurement Notes

Verify the specific datasheet version for the CDBFN160-HF to confirm exact thermal resistance values and mechanical dimensions. Ensure compatibility with automated surface-mount assembly processes due to the small SOD-323 footprint. Cross-reference the operating temperature range with your system's environmental requirements to guarantee reliability under all expected load conditions.

Selection Notes

Select this component when space constraints require a low-profile SOD-323 package instead of standard SOD-123. It is suitable for applications demanding fast switching speeds and low forward voltage drops at 60 V reverse voltage ratings. Consider the 30 A surge current capability for circuits experiencing transient loads.

Part Context

This part belongs to Comchip Technology's CDBFN series of Schottky barrier rectifiers. The series is characterized by batch process designs that enhance power dissipation and thermal resistance. These devices are engineered specifically for low-profile surface-mounted applications to optimize printed circuit board real estate while maintaining high efficiency.

Replacement Considerations

Direct substitutes must match the 60 V reverse voltage, 1 A forward current, and SOD-323 package. Verify that alternative Schottky diodes offer comparable forward voltage drops and switching speeds to maintain circuit performance without modification.
