Overview
The CD214B-B120LF is a Schottky Barrier Rectifier Chip Diode manufactured by Bourns Inc. It features a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 20 V. The device utilizes a DO-214AA (SMB) surface-mount package with lead-free terminations. Electrical characteristics include a typical junction capacitance of 110 pF, a maximum instantaneous forward voltage of 0.7 V at 1 A, and a peak forward surge current rating of 30 A. The component operates within a temperature range of -55 °C to +125 °C.
Feature Summary
- Schottky barrier technology enables high-speed switching for low voltage applications
- Compact SMB (DO-214AA) molded plastic package minimizes PCB footprint
- Lead-free construction compliant with RoHS Directive 2002/95/EC
Applications
- Low voltage high frequency inverters
- Free wheeling circuits
- Polarity protection
Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to confirm termination plating and compliance status. Confirm that the requested quantity aligns with standard reel packaging specifications. Ensure compatibility with standard pick-and-place equipment due to the flat configuration design.
Selection Notes
Select this component when a 1 A forward current and 20 V reverse voltage rating are required in a compact surface-mount form factor. Consider the thermal resistance and derating curves for high ambient temperature environments. Verify that the 110 pF junction capacitance meets the frequency requirements of the target circuit design.
Part Context
This component belongs to the CD214B-B series of Schottky Barrier Rectifiers from Bourns. The series offers various voltage ratings ranging from 20 V to 60 V while maintaining a consistent 1 A forward current capability. All variants share the same DO-214AA physical package dimensions and electrical interface characteristics.
Replacement Considerations
Compatible substitutes within the same series include CD214B-B130LF, CD214B-B140LF, CD214B-B150LF, and CD214B-B160LF. These parts share identical physical dimensions and current ratings but offer higher reverse voltage capabilities.
