Overview
The CD214B-B240LF is a single Schottky barrier rectifier manufactured by Bourns Inc. It utilizes silicon technology and is housed in the DO-214AC (SMA) surface-mount package. The device features a maximum repetitive peak reverse voltage of 40 V and supports an average forward current of 2 A. Key electrical characteristics include a maximum forward voltage of 490 mV, a non-repetitive peak forward surge current of 50 A, and a maximum reverse current of 25 uA. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Schottky barrier construction for low forward voltage drop
- Silicon planar design compliant with JEDEC standards
- Lead-free termination finish compatible with RoHS directives
Applications
- High-frequency rectification in power supply circuits
- Reverse polarity protection in consumer electronics
- Clamping and free-wheeling diodes in DC-DC converters
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm terminal finish and packaging configuration. Ensure the component meets the required environmental compliance standards for the target assembly process. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component for applications requiring efficient high-speed switching with minimal power loss. The 40 V rating suits low-voltage systems, while the 2 A current capacity handles moderate load requirements. The SMA package offers a compact footprint suitable for space-constrained printed circuit board layouts.
Part Context
This component belongs to the CD214B-B series of Schottky diodes from Bourns. The series is designed to address the miniaturization demands of modern electronic devices by providing robust performance in small surface-mount packages. It serves as a standard solution for general-purpose rectification where speed and efficiency are prioritized over high voltage blocking capabilities.
Replacement Considerations
Consult official substitution guides for equivalent Schottky rectifiers with matching 40 V ratings, 2 A current capacity, and DO-214AC packaging. Verify thermal and electrical compatibility before replacing.
