Overview
The CD214B-B220LF is a Schottky barrier rectifier manufactured by Bourns Inc. It features a single diode configuration in a DO-214AC (SMB) surface-mount package. Key electrical parameters include a maximum repetitive peak reverse voltage of 20 V and an average forward rectified current of 2 A. The device exhibits a low forward voltage drop of 500 mV at rated current and supports a high non-repetitive peak forward surge current of 50 A. Operating temperature range spans from -55 °C to +125 °C junction temperature, with a maximum reverse leakage current of 500 µA.
Feature Summary
- Schottky barrier technology for low forward voltage drop and fast switching performance
- Compact DO-214AC surface-mount package design for space-constrained PCB layouts
- High surge current capability suitable for transient protection applications
Applications
- General purpose rectification in consumer electronics
- Power supply input rectification circuits
- Free-wheeling diodes in DC-DC converters
Procurement Notes
Verify the specific suffix 'LF' indicates lead-free compliance and RoHS status against the manufacturer's latest datasheet revision. Confirm availability as distribution channels may list this part as obsolete or end-of-life. Ensure the DO-214AC footprint matches your PCB design requirements before ordering.
Selection Notes
Select this component when a 20 V rating and 2 A continuous current are required in a compact SMB package. Compare forward voltage characteristics against alternative Schottky diodes to ensure efficiency targets are met. Verify thermal management capabilities for the intended operating environment within the specified temperature range.
Part Context
This part belongs to the Bourns CD214 series of chip rectifiers, designed for general-purpose applications. The series offers various voltage ratings and current capacities in small surface-mount packages to support miniaturization trends in modern electronic devices.
Replacement Considerations
Check for direct pin-compatible substitutes with identical DO-214AC packaging and matching 20 V / 2 A specifications. Verify that any replacement maintains equivalent forward voltage and reverse leakage current characteristics to ensure circuit compatibility.
