CD214A-B140R

Overview

The CD214A-B140R 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 40 V. The device operates within a junction temperature range of -55 °C to +125 °C. Electrical characteristics include a typical instantaneous forward voltage of 0.50 V at 1 A and a DC reverse current of 0.2 mA at rated voltage. The component utilizes a DO-214AC (SMA) compatible package with a typical junction capacitance of 110 pF.

Feature Summary

• UL 94V-0 classification

Applications

• Switch Mode Power Supplies
• Portable equipment batteries
• High frequency rectification
• DC/DC Converters
• Telecommunications

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer before procurement, as specifications are subject to change without notice. Confirm that the intended application environment falls within the specified operating temperature range and does not involve life-critical or high-risk scenarios where failure could result in severe consequences. Ensure compatibility with standard surface mount pick-and-place equipment during assembly.

Selection Notes

Select this component for applications requiring compact rectification solutions with low power loss and high efficiency. The choice between standard and low forward voltage variants depends on the specific thermal management requirements and voltage drop constraints of the circuit design. Verify that the 1 A average forward current rating adequately supports the load conditions and surge currents expected in the target system.

Part Context

This part belongs to the CD214A-B1xR series of Schottky Barrier Rectifier Chip Diodes from Bourns. The series addresses the industry demand for smaller electronic components in portable communications, computing, and video equipment. These diodes offer a silicon solution with minimal packaging overhead in a format compatible with DO-214AC size standards.

Replacement Considerations

Compatible substitutes within the same series include CD214A-B120R, CD214A-B160R, and CD214A-B1100R. Selection among these alternatives should be based on the required repetitive peak reverse voltage ratings of 20 V, 60 V, or 100 V respectively, while maintaining the 1 A forward current capability.
