Procurement Notes
Verify the specific part number against official manufacturer documentation before procurement. Confirm that the component meets all required electrical parameters for your application. Check for any updates to the datasheet or compliance certifications. Ensure compatibility with your assembly process and environmental conditions. Review the manufacturer's legal disclaimers regarding product suitability and liability.
Selection Notes
Select this component for applications requiring fast switching speeds and high voltage ratings up to 800 V. Consider the 2 A current capacity and thermal resistance when designing heat dissipation strategies. Evaluate the reverse recovery time for high-frequency operation requirements. Ensure the operating temperature range aligns with your system's environmental constraints. Verify package compatibility with your PCB layout and mounting specifications.
Part Context
The CD214B-FS2K belongs to the CD214B-FS2x series of fast response rectifier chip diodes from Bourns. This series is designed for compact electronic components in portable communications, computing, and video equipment. The glass passivated rectifiers offer a choice of repetitive peak reverse voltages ranging from 200 V to 800 V, providing flexibility for various rectification applications in a standard SMB package format.
Replacement Considerations
Consult the official Bourns selector guide for equivalent parts within the CD214B-FS2x series. Verify that any substitute component matches the 800 V reverse voltage and 2 A forward current ratings. Ensure the replacement maintains similar reverse recovery time and forward voltage characteristics. Cross-reference package dimensions and pin configurations for mechanical compatibility.
