Overview
The CD214B-B350LF is a Schottky Barrier Rectifier Chip Diode manufactured by Bourns Inc. It features a single diode configuration in an SMB (DO-214AA) surface-mount package. The device supports a repetitive peak reverse voltage of 50 V and an average forward current of 3 A. Key electrical parameters include a maximum forward voltage of 0.7 V at 3 A, a maximum reverse current of 0.5 mA at rated voltage, and a typical junction capacitance of 250 pF. It withstands a surge peak forward current of 100 A and operates within a junction temperature range of -55 °C to +125 °C.
Feature Summary
- Utilizes a compact SMB (DO-214AA) molded plastic package for PCB real estate savings.
- Provides high current capability with a 3 A average forward current rating.
- Features low forward voltage drop characteristics suitable for rectification applications.
- Compliant with RoHS directives and utilizes 100% tin terminations.
Applications
- Rectification in portable communications equipment
- Power supply circuits in computing devices
- Video equipment power management
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm the specific suffix LF indicates lead-free, 100% tin terminations compliant with RoHS standards. Check datasheet revisions as specifications are subject to change without notice. Ensure storage conditions remain within the specified temperature limits to maintain device integrity prior to assembly.
Selection Notes
Select this component for designs requiring a 50 V reverse voltage rating with a 3 A continuous current capacity. The SMB package is appropriate for standard pick-and-place automated assembly processes. Consider the 0.7 V forward voltage characteristic when calculating power dissipation. Verify thermal resistance requirements against the application's ambient temperature constraints.
Part Context
This part belongs to the CD214B-B320 through B360 series of Schottky Barrier Rectifiers. The series offers various voltage ratings from 20 V to 60 V while maintaining a consistent 3 A current rating and SMB package form factor. The CD214B-B350LF specifically addresses applications needing a 50 V blocking capability within this standardized product line.
Replacement Considerations
The datasheet recommends the CD214B-B3xR Series as the replacement for new designs. Specific substitutes include CD214B-B320B, CD214B-B330B, CD214B-B340B, CD214B-B350B, and CD214B-B360B.
