Overview
The CD214A-B320LF is a Schottky Barrier Rectifier Chip Diode from Bourns Inc., housed in an SMA (DO-214AC) surface-mount package. It features a repetitive peak reverse voltage of 20 V and an average forward current rating of 3 A. The device exhibits a maximum forward voltage of 0.5 V at 3 A and a typical junction capacitance of 250 pF measured at 1.0 MHz. It supports a surge peak forward current of 100 A and operates within a junction temperature range of -55 °C to +125 °C.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- SMA (DO-214AC) molded plastic case for PCB real estate savings
- Flat configuration minimizes roll-away on standard pick-and-place equipment
- RoHS compliant with lead-free terminations
Applications
- Rectification in portable communications equipment
- Power supply circuits in computing devices
- Video equipment power management
Procurement Notes
Verify component authenticity through authorized Bourns distributors or certified partners. Confirm RoHS compliance status and lead-free termination specifications against the latest datasheet revisions. Ensure storage conditions remain within the specified temperature range to maintain device integrity prior to assembly.
Selection Notes
Select this component for applications requiring a 20 V reverse voltage rating and 3 A continuous forward current capability. The SMA package is suitable for space-constrained designs needing surface-mount integration. Consider thermal resistance characteristics when designing heat dissipation paths for high-duty cycle operations.
Part Context
This part belongs to the CD214A-B3xx series of Schottky Barrier Rectifiers, which offer various voltage ratings from 20 V to 60 V. The series is designed to meet JEDEC standards and provides compact solutions for modern electronic devices. The specific B320 variant targets lower voltage rectification needs within this family.
Replacement Considerations
The datasheet identifies the CD214A-B3xR Series as the recommended replacement for this obsolete component. Verify pinout compatibility and electrical parameter equivalence before substitution.
