Overview
The CD214A-B170LF 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 70 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. It operates within a junction temperature range of -55 °C to +125 °C and withstands a surge peak forward current of 30 A.
Feature Summary
- Utilizes a compact SMA (DO-214AC) molded plastic package for PCB real estate savings.
- Provides very low forward voltage drop for efficient power rectification.
- Conforms to JEDEC standards and is compatible with standard pick-and-place equipment.
- Features a flat configuration to minimize rollaway during automated assembly.
Applications
- Rectification in portable communications devices
- Power protection circuits in computing systems
- Voltage clamping in video equipment
Procurement Notes
Verify component authenticity through authorized Bourns distributors or certified suppliers. Confirm RoHS compliance status and lead-free termination specifications against the latest datasheet revision. Ensure storage conditions remain within specified limits to maintain device integrity prior to soldering.
Selection Notes
Select this component for applications requiring a 70 V reverse voltage rating and 1 A continuous forward current in a surface-mount format. Consider the specific forward voltage and leakage current parameters relative to thermal management requirements. Evaluate compatibility with existing footprint designs utilizing the DO-214AC package dimensions.
Part Context
This part belongs to the CD214A-B1xx series of Schottky Barrier Rectifier Chip Diodes from Bourns. The series offers various voltage ratings from 20 V to 100 V within the same SMA package. The 'LF' suffix indicates 100% tin terminations compliant with RoHS directives. This specific model provides a 70 V blocking capability within that standardized lineup.
Replacement Considerations
The datasheet explicitly recommends the CD214A-B1xR Series as the replacement for new designs. Verify pinout compatibility and electrical parameter equivalence when substituting this discontinued part with the recommended R-series alternative.
FAQ
What is the maximum repetitive peak reverse voltage for the CD214A-B170LF?
The maximum repetitive peak reverse voltage (VRRM) is 70 V.
Does the CD214A-B170LF support automatic placement?
Yes, the device conforms to JEDEC standards and its flat configuration minimizes rollaway, making it easy to handle on standard pick-and-place equipment.
