Overview
The CD214B-F350 is a surface mount fast response rectifier manufactured by Bourns Inc. It features a glass passivated junction in a compact DO-214AA (SMB) package. The device provides a maximum average forward rectified current of 3.0 A and a maximum repetitive peak reverse voltage of 50 V. Key electrical characteristics include a typical junction capacitance of 10 pF, a maximum instantaneous forward voltage of 0.95 V at 1 A, and a maximum reverse recovery time of 35 ns. It operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Glass passivated junction chip for reliable rectification
- Low reverse leakage current and low forward voltage drop
- High current capability with 3.0 A average forward rating
- Fast response performance with minimal reverse recovery time
Applications
- Portable communications equipment
- Computing systems
- Video equipment power supplies
Procurement Notes
Verify component authenticity through authorized Bourns channels or certified distributors. Confirm RoHS compliance status matches the specific manufacturing batch. Ensure storage conditions adhere to moisture sensitivity levels defined in JEDEC standards. Validate that the received part marking corresponds exactly to the ordered model number before integration into production lines.
Selection Notes
Select this component for applications requiring high-speed switching and robust current handling in space-constrained designs. The SMB package offers significant PCB real estate savings compared to larger alternatives. Consider thermal derating curves when operating near maximum ambient temperatures. Verify compatibility with standard pick-and-place equipment due to the flat configuration minimizing roll-away risks during automated assembly.
Part Context
This device belongs to the CD214B-F3xx series of surface mount fast response rectifiers from Bourns. These components are designed to meet the demands of modern electronics for smaller form factors without sacrificing performance. The series utilizes a molded plastic package compliant with UL flammability classifications. They conform to JEDEC standards for mechanical dimensions and electrical testing methods.
Replacement Considerations
The datasheet explicitly states that the CD214B-F350~F3600 series is not recommended for new designs. The Model CD214B-FS3x Series is identified as the recommended replacement. Engineers should evaluate the FS3x series specifications to ensure equivalent or improved performance for future implementations.
