Procurement Notes
Verify the specific part number against the manufacturer's official datasheet to confirm electrical ratings and package dimensions. Ensure compliance with RoHS directives and UL requirements relevant to the target application environment. Confirm availability status directly with authorized distributors or the manufacturer, as supply conditions may change without notice.
Selection Notes
Select this component for applications requiring high-speed rectification in compact designs. The 400 V rating suits intermediate voltage levels, while the 3 A current capacity supports moderate power loads. Consider the low thermal resistance and wide operating temperature range for environments with significant heat generation or extreme ambient conditions.
Part Context
This component belongs to the CD214B-FS3x series of fast response rectifier chip diodes from Bourns. The series offers various voltage ratings including 200 V, 600 V, and 800 V variants, all sharing the same SMB package format and 3 A current capability. These diodes are designed to meet the miniaturization demands of modern portable electronics and computing devices.
Replacement Considerations
Compatible substitutes within the same series include CD214B-FS3D (200 V), CD214B-FS3J (600 V), and CD214B-FS3K (800 V). Verify that the alternative voltage rating meets the circuit's peak reverse voltage requirements before substitution.
