CD214B-FS2G

Overview

The Bourns CD214B-FS2G is a glass passivated fast response rectifier chip diode housed in a compact DO-214AA (SMB) compatible package. It provides a maximum average forward current of 2 A and a repetitive peak reverse voltage rating of 400 V. The device features a typical reverse recovery time of 35 ns and a maximum instantaneous forward voltage of 1.25 V at 2 A. Operating junction temperatures range from -65 °C to +175 °C, with a maximum peak forward surge current capability of 50 A.

Feature Summary

• Glass passivation for enhanced stability
• Low profile surface mount design
• High efficiency with low power loss
• UL 94V-0 classification

Applications

• Switching Mode Power Supplies
• Portable equipment batteries
• DC/DC Converters
• Telecommunications

Procurement Notes

Verify the specific datasheet revision against the manufacturer's official technical library before finalizing designs. Confirm that the component meets all applicable RoHS compliance directives and lead-free manufacturing requirements relevant to your target market regulations. Ensure proper handling procedures are followed during assembly.

Selection Notes

Select this component when a 400 V reverse voltage rating and 2 A continuous forward current are required within a standard SMB footprint. Consider its 35 ns reverse recovery time for high-frequency rectification tasks. Evaluate thermal resistance parameters to ensure adequate heat dissipation under expected load conditions.

Part Context

This part belongs to the CD214B-FS2x series of fast response rectifiers. Other variants in the series include the FS2D (200 V), FS2J (600 V), and FS2K (800 V). All share identical physical dimensions and electrical characteristics except for their specific voltage ratings.

Replacement Considerations

Direct substitutes must match the 400 V rating, 2 A current capacity, and DO-214AA package. Verify equivalent reverse recovery times and forward voltage drops to maintain circuit performance without modification.
