Overview
The CD214A-B220LR is a Schottky barrier rectifier chip diode manufactured by Bourns Inc. It utilizes silicon technology and is housed in a DO-214AC (SMA) surface-mount package with two pins. The device supports a maximum average forward current of 2 A and a maximum repetitive peak reverse voltage of 20 V. Key electrical parameters include a typical instantaneous forward voltage of 0.39 V at 2 A, a maximum DC reverse current of 1 mA, and a typical junction capacitance of 115 pF. It operates within a temperature range of -55 °C to +125 °C.

- RoHS compliant construction
- UL 94V-0 classification for flame retardancy
- High efficiency with low power loss characteristics
Applications
- Switching mode power supplies
- Portable equipment batteries
- DC/DC converters
- Telecommunications systems
- High frequency rectification
Procurement Notes
Verify the specific ordering suffix 'L' indicates the low forward voltage variant when sourcing replacements or verifying inventory. Confirm that the component is supplied in tape and reel packaging containing 3,000 units per reel. Ensure compatibility with automated SMD assembly processes due to the flat configuration of the DO-214AC package.
Selection Notes
Select this component for applications requiring high efficiency and low forward voltage drop at 2 A loads. The 20 V rating suits low-voltage rectification tasks. Consider the thermal resistance values for heat dissipation planning on PCB copper pads. Verify that the operating temperature range meets the environmental requirements of the target electronic system.
Part Context
This part belongs to the CD214A-B2xR series of Schottky Barrier Rectifier Chip Diodes from Bourns. The series addresses the industry demand for miniaturized components in portable communications and computing devices. The 'L' suffix specifically denotes the low forward voltage version within the 20 V rated models of this product line.
Replacement Considerations
Compatible substitutes within the same series include CD214A-B220R, which shares identical ratings but lacks the low forward voltage specification.
FAQ
What does the 'L' suffix signify in the model number CD214A-B220LR?
The 'L' suffix indicates that the device features a low forward voltage characteristic compared to standard variants.
What is the typical junction capacitance for this diode?
The typical junction capacitance is 115 pF, measured at VR = 4 V and f = 1.0 MHz.
