Overview
The CD214A-B140LR is a Schottky barrier rectifier chip diode from the CD214A-B1xR series, manufactured by Bourns Inc. It utilizes a compact DO-214AC (SMA) compatible package and features a low forward voltage characteristic. The device supports a maximum average forward current of 1 A and a maximum repetitive peak reverse voltage of 40 V. Key electrical parameters include a typical instantaneous forward voltage of 0.38 V at 1 A and a DC reverse current of 1.0 mA at rated voltage. It operates within a junction temperature range of -55 °C to +125 °C.
Feature Summary
- Low profile design suitable for space-constrained portable electronics
- RoHS compliant construction with UL 94V-0 classification
- Optimized thermal resistance for efficient heat dissipation
- High efficiency operation due to reduced power loss
Applications
- Switch mode power supplies
- Portable equipment batteries
- DC/DC converters
- Telecommunications systems
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required low forward voltage variant. Ensure compliance with local environmental regulations regarding RoHS standards. Validate packaging specifications against production requirements before finalizing orders.
Selection Notes
Select this component when low forward voltage drop is critical for system efficiency. The SMA-compatible footprint allows for standard surface mount assembly processes. Consider the thermal characteristics for high-density PCB layouts. Verify that the 40 V reverse voltage rating aligns with circuit operating conditions.
Part Context
This part belongs to the CD214A-B1xR series of Schottky barrier rectifiers designed for miniaturized electronic applications. The series offers various voltage ratings while maintaining a consistent 1 A forward current capability. The 'L' suffix specifically denotes the low forward voltage version, distinguishing it from standard variants in terms of electrical performance.
Replacement Considerations
Compatible substitutes within the same series include CD214A-B140R, which shares identical mechanical dimensions but differs in forward voltage characteristics. Cross-referencing datasheets is essential to ensure electrical compatibility during replacement scenarios.
