CD214B-S2J

Overview

The CD214B-S2J is a glass passivated rectifier chip diode from the CD214B-S2x series, manufactured by Bourns Inc. It utilizes a compact SMB (DO-214AA) compatible package designed for surface-mount applications. The device provides a maximum average forward rectified current of 2 A and a maximum repetitive peak reverse voltage of 600 V. Key electrical characteristics include a maximum instantaneous forward voltage of 1.00 V at 2 A and a typical junction capacitance of 14 pF. It supports an operating junction temperature range from -65 °C to +175 °C.

Feature Summary

• Glass passivation ensures stable performance in rectification applications
• Low profile SMB-compatible footprint suitable for space-constrained designs
• High efficiency operation with low power loss characteristics
• UL 94V-0 rating for enhanced safety compliance

Applications

• Switch Mode Power Supplies
• DC/DC Converters
• Portable equipment batteries
• Telecommunications
• High frequency rectification

Procurement Notes

Verify component authenticity through authorized Bourns distributors or direct channels. Confirm datasheet revision status prior to implementation. Ensure ordering suffixes match specific voltage ratings. Validate RoHS and Halogen-free compliance requirements against project specifications. Cross-reference part markings with official documentation to prevent counterfeit risks.

Selection Notes

Select this component when a 600 V reverse voltage rating is required alongside a 2 A continuous forward current capacity. The SMB package offers a balance between thermal dissipation and board space efficiency compared to smaller footprints. Consider the 1.00 V forward voltage drop for power loss calculations in high-current paths. Evaluate thermal resistance parameters for heat management in enclosed environments.

Part Context

This diode belongs to the CD214B-S2x family of glass passivated rectifiers. The series includes variants with different peak reverse voltage ratings, specifically 200 V, 400 V, 800 V, and 1000 V, sharing the same physical package and general electrical structure. The S2J designation specifically identifies the 600 V version within this standardized lineup.

Replacement Considerations

Direct substitutes must match the DO-214AA/SMB package, 2 A forward current, and 600 V reverse voltage specifications. Verify that alternative components maintain comparable forward voltage drops and junction temperature limits. Check for identical pinout configurations and mounting dimensions to ensure mechanical compatibility.
