Overview
The CD214A-B240R is a Schottky barrier rectifier chip diode manufactured by Bourns Inc. It features a maximum average forward current of 2 A and a maximum repetitive peak reverse voltage of 40 V. The device utilizes a DO-214AC (SMA) compatible surface-mount package. Electrical characteristics include a typical instantaneous forward voltage of 0.5 V at 2 A and a DC reverse current of 0.2 mA at rated voltage. The component operates within a junction temperature range of -55 °C to +125 °C and supports a peak forward surge current of 50 A.
Feature Summary
- RoHS compliant construction
- Low profile design
- UL 94V-0 classification
Applications
- Switching Mode Power Supplies
- Portable equipment batteries
- High frequency rectification
- DC/DC Converters
- Telecommunications
Procurement Notes
Verify the specific datasheet version for the CD214A-B240R before procurement, as specifications are subject to change without notice. Confirm that the ordering suffix 'R' corresponds to the tape and reel packaging format containing 3,000 units per reel. Ensure compatibility with standard pick-and-place equipment due to the flat configuration of the DO-214AC package. Check for any regional restrictions or compliance requirements relevant to the target market.
Selection Notes
Select the CD214A-B240R when a 2 A forward current rating and 40 V reverse voltage capability are required in a compact SMA-compatible footprint. Consider this component for high-efficiency applications due to its low forward voltage drop compared to standard silicon rectifiers. Evaluate the thermal resistance parameters if operating near the maximum junction temperature limits. Compare against other series variants like the LR models if lower forward voltage is prioritized over standard performance metrics.
Part Context
This component belongs to the CD214A-B2xR series of Schottky Barrier Rectifier Chip Diodes from Bourns. The series addresses the industry demand for miniaturization in portable communications, computing, and video equipment. These diodes offer a silicon solution with minimal packaging overhead, utilizing leadless packages that save PCB real estate while maintaining compatibility with automated manufacturing processes.
Replacement Considerations
Compatible substitutes within the same family include CD214A-B220R and CD214A-B260R, which share identical physical dimensions and electrical ratings except for their specific repetitive peak reverse voltage values of 20 V and 60 V respectively.
