Overview
The CD214A-B120LF is a Schottky Barrier Rectifier Chip Diode manufactured by Bourns Inc. It features a DO-214AC (SMA) surface-mount package with a single diode configuration. The device supports an average forward current of 1 A and a repetitive peak reverse voltage of 20 V. Key electrical parameters include a maximum forward voltage of 0.5 V at 1 A, a maximum reverse current of 500 µA at rated voltage, and a typical junction capacitance of 110 pF. The component operates within a junction temperature range of -55 °C to +125 °C and has a storage temperature range of -55 °C to +150 °C.
Feature Summary
- Utilizes a compact SMA (DO-214AC) molded plastic package for PCB real estate savings.
- Provides very low forward voltage drop characteristics suitable for rectification applications.
- Features flat configuration to minimize roll-away on standard pick-and-place equipment.
- Conforms to JEDEC standards and RoHS directives.
Applications
- Rectification in portable communications equipment
- Power supply circuits in computing devices
- Video equipment power management
Procurement Notes
Verify the specific part number suffix against official manufacturer documentation before procurement. Confirm that the LF designation corresponds to lead-free terminations as specified in the ordering guide. Ensure compatibility with existing design specifications regarding package dimensions and thermal resistance values. Check for any product discontinuation notices or recommended replacement series updates from the manufacturer.
Selection Notes
Select this component for applications requiring a 1 A continuous forward current and 20 V reverse voltage rating in a small surface-mount footprint. Consider the 0.5 V maximum forward voltage drop for efficiency requirements. Verify that the operating environment stays within the specified junction temperature limits. Evaluate the need for RoHS compliance if required by the end-product regulations.
Part Context
This component belongs to the CD214A-B1xx series of Schottky Barrier Rectifiers. The series offers various voltage ratings from 20 V to 100 V in the same SMA package format. The datasheet indicates that while this model is available, it is not recommended for new designs, suggesting the CD214A-B1xR series as the preferred alternative for future projects.
Replacement Considerations
The manufacturer recommends the CD214A-B1xR Series as the replacement for this model. Designers should consult the datasheet for the CD214A-B1xR series to verify pinout compatibility and electrical parameter equivalence before substitution.
