Overview
The CD214A-B120LR is a Schottky barrier rectifier chip diode manufactured by Bourns Inc. It features a maximum average forward current of 1 A and a maximum repetitive peak reverse voltage of 20 V. The device utilizes a DO-214AC (SMA) compatible surface mount package. Key electrical parameters include a typical instantaneous forward voltage of 0.37 V at 1 A, a maximum DC reverse current of 1.0 mA, and a typical junction capacitance of 110 pF. Thermal resistance from junction to ambient is specified at 55 °C/W.
Feature Summary
- Low profile design suitable for compact electronic components
- RoHS compliant construction
- UL 94V-0 classification
- High efficiency with low power loss
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 the 'R' suffix corresponds to tape and reel packaging requirements. Ensure compatibility with standard pick-and-place equipment during assembly planning. Cross-reference the latest datasheet revision for any updates to absolute maximum ratings or thermal characteristics before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring high-frequency rectification where low forward voltage drop is critical for efficiency. The 20 V rating suits low-voltage DC/DC converter designs. Verify that the 1 A continuous current capability meets the load requirements. Consider the 55 °C/W thermal resistance for heat dissipation analysis in densely packed PCB layouts.
Part Context
This part belongs to the CD214A-B1xR series of Schottky Barrier Rectifier Chip Diodes. The series offers choices of repetitive peak reverse voltages ranging from 20 V to 100 V. All variants share the same compact SMA-compatible footprint, designed to minimize rollaway and support automated manufacturing processes for portable communications and computing equipment.
Replacement Considerations
CD214A-B120R serves as a direct alternative within the same series, differing primarily in having a higher typical forward voltage of 0.47 V compared to the 0.37 V of the LR variant.
