Overview
The CD214B-B250LF is a Schottky barrier rectifier diode manufactured by Bourns Inc. It features a 50V maximum repetitive peak reverse voltage and a 2A average forward rectified current rating. The device utilizes a surface-mount DO-214AA (SMB) package, designed for efficient thermal performance and compact circuit layouts. It exhibits low forward voltage drop and minimal reverse leakage current, specified at 500µA at 50V. This component is engineered for high-speed switching applications requiring reliable rectification in space-constrained environments.
Feature Summary
- Schottky barrier construction for fast switching speeds
- Low forward voltage drop to minimize power loss
- Surface-mount DO-214AA (SMB) package design
Applications
- DC-DC converter output rectification
- Power supply freewheeling diodes
- Reverse polarity protection circuits
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with Bourns Inc. or authorized distributors before procurement. Confirm that the DO-214AA package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system's thermal profile. Check for any lifecycle status changes, as availability may vary across regions.
Selection Notes
Select this component when a 50V reverse voltage rating and 2A current capacity are required in a SMB package. Consider its low forward voltage characteristics for efficiency-critical designs. Evaluate the thermal resistance of the DO-214AA package against your heat dissipation needs. Compare reverse leakage specifications if low standby power consumption is critical for the application.
Part Context
This part belongs to Bourns' CD214B series of Schottky barrier rectifiers. The series offers various voltage ratings within the same SMB package form factor. These diodes are commonly used in general-purpose rectification tasks where size and switching speed are prioritized over high voltage blocking capabilities. The LF suffix indicates lead-free composition compliant with environmental directives.
Replacement Considerations
Consult official substitution guides for equivalent Schottky diodes with matching 50V/2A ratings in DO-214AA packages. Verify pinout compatibility and thermal characteristics before replacing. Cross-reference with other manufacturers offering SMB Schottky rectifiers to ensure functional equivalence in your specific circuit design.
