Overview
The CD214A-B190LF is a Schottky barrier rectifier chip diode manufactured by Bourns Inc. It features a single configuration in the SMA (DO-214AC) surface-mount package. The device supports an average forward current of 1 A and a repetitive peak reverse voltage of 90 V. Electrical characteristics include a maximum forward voltage of 0.79 V at 1 A, a maximum reverse current of 500 µA at rated voltage, and a typical junction capacitance of 30 pF. The component operates within a junction temperature range of -55 °C to +125 °C.
Feature Summary
- Utilizes a compact SMA (DO-214AC) leadless package for PCB real estate savings
- Provides low forward voltage drop for improved efficiency
- Flat configuration minimizes rollaway during automated assembly
Applications
- Rectification in portable communications equipment
- Power protection circuits in computing devices
- Low power signal rectification in video equipment
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure storage conditions remain within specified limits to maintain performance integrity prior to installation.
Selection Notes
Select this component for applications requiring a 90 V reverse voltage rating with a 1 A continuous forward current capacity. Consider the 0.79 V forward voltage characteristic for thermal management. Verify that the SMA footprint aligns with existing board layouts and pick-and-place equipment capabilities.
Part Context
This part belongs to the CD214A-B1xx series of Schottky Barrier Rectifiers. The series offers various voltage ratings from 20 V to 100 V within the same DO-214AC package format. The 'L' suffix indicates a low forward voltage variant, which is not present in the B190 model. The series is designed for high-speed switching and rectification tasks.
Replacement Considerations
The datasheet explicitly recommends the CD214A-B1xR Series as the replacement for this model. Verify pinout compatibility and electrical parameter equivalence before substitution.
