Overview
The CD214A-B320LR is a Schottky Barrier Rectifier Chip Diode from Bourns, housed in a compact DO-214AC (SMA) package. It features a maximum average forward current of 3 A and a repetitive peak reverse voltage of 20 V. The device offers low forward voltage characteristics, with a typical instantaneous forward voltage of 0.3 V at 1 A and 0.39 V at 3 A. It supports a peak forward surge current of 80 A and operates within a junction temperature range of -55 to +125 °C.
Feature Summary
- Low power loss and high efficiency design
- RoHS compliant construction
- UL 94V-0 classification for flame retardancy
- Low profile surface mount configuration
Applications
- Switch Mode Power Supplies
- Portable equipment batteries
- High frequency rectification
- DC/DC Converters
- Telecommunications
Procurement Notes
Verify the specific ordering suffix 'L' indicates the low forward voltage variant when sourcing. Confirm that the component is supplied in tape and reel packaging format. Ensure compatibility with standard SMD pick-and-place equipment due to the flat package configuration. Check for RoHS compliance status relative to current manufacturing standards.
Selection Notes
Select this component for applications requiring efficient rectification in space-constrained designs. The DO-214AC package provides a balance of thermal performance and footprint size. Consider the low forward voltage specification for minimizing conduction losses in low-voltage DC systems. Verify thermal resistance requirements against the intended PCB copper pad layout.
Part Context
This part belongs to the CD214A-B3xR series of Schottky Barrier Rectifiers designed for portable communications and computing equipment. The series addresses industry demands for smaller electronic components by offering silicon diodes in minimal packaging overhead. It serves as a modern alternative to larger through-hole rectifiers in high-density circuit board layouts.
Replacement Considerations
Compatible substitutes include other Schottky diodes in the DO-214AC package with similar 3 A current ratings and 20 V reverse voltage capabilities. Ensure replacement parts match the low forward voltage specifications if efficiency is critical. Verify that alternative components meet the same operating temperature and surge current requirements.
