Overview
The CDBC520-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a DO-214AB (SMC) package and provides an average forward current of 5A with a repetitive peak reverse voltage of 20V. The device exhibits a maximum forward voltage drop of 500mV at 5A and a low reverse leakage current of 500µA at 20V. It supports a forward surge current of 125A and operates within a junction temperature range of -50°C to 175°C.
Feature Summary
- Utilizes Schottky technology for majority carrier conduction, ensuring fast switching speeds and minimal reverse recovery time.
- Engineered with a planar die construction to enhance reliability and withstand high thermal stress during operation.
- Manufactured using halogen-free materials, complying with environmental standards for electronic components.
Applications
- High-frequency rectification in DC-DC converter circuits
- Power supply input protection against reverse polarity
- Free-wheeling diodes in inductive load switching applications
Procurement Notes
Verify the specific ordering suffix to confirm packaging type, such as tape and reel or cut tape, as these affect handling procedures. Confirm RoHS compliance status and halogen-free certification through official manufacturer documentation before integration into regulated assemblies. Ensure the DO-214AB footprint matches the design layout precisely.
Selection Notes
Select this component when a low forward voltage drop is critical for efficiency in 5A applications. The 20V rating suits low-voltage systems requiring robust surge handling. Consider the SMC package size for adequate heat dissipation compared to smaller packages like SMA or SMB in similar current scenarios.
Part Context
This part belongs to Comchip Technology's CDBC series of surface-mount Schottky rectifiers. The series offers various voltage ratings while maintaining consistent 5A current capabilities across different package options. The CDBC520-HF specifically addresses low-voltage, high-current requirements in compact form factors.
Replacement Considerations
Direct substitutes must match the 5A current rating, 20V reverse voltage, and DO-214AB package. Verify equivalent forward voltage and reverse leakage specifications to ensure circuit performance compatibility without redesign.
