CD214B-S2D

Overview

The CD214B-S2D is a glass passivated rectifier chip diode from the Bourns CD214B-S2x Series, housed in a compact SMB/DO-214AA compatible package. It provides a maximum average forward rectified current of 2 A and a maximum repetitive peak reverse voltage of 200 V. The device supports a maximum peak forward surge current of 50 A for an 8.3 ms single half sine-wave. Electrical characteristics include a maximum instantaneous forward voltage of 1.00 V at 2 A and a typical junction capacitance of 14 pF. Operating and storage temperature ranges extend from -65 °C to +175 °C.

Feature Summary

• Glass passivation protects the PN junction against mechanical stress and moisture
• Low profile design facilitates high-density PCB layouts
• High efficiency operation with low power loss during rectification
• Halogen-free construction meets environmental safety standards

Applications

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

Procurement Notes

Verify component authenticity by checking markings against official datasheet specifications. Confirm RoHS compliance status and halogen-free designation prior to integration. Ensure ordering suffixes match required voltage ratings. Validate packaging format matches production requirements. Review legal disclaimers regarding application suitability and liability limitations before procurement.

Selection Notes

Select this component when a 200 V reverse voltage rating is required alongside a 2 A continuous forward current capacity. The SMB package offers a balance between current handling and board space constraints. Consider thermal resistance values for heat dissipation planning. Evaluate junction capacitance for high-frequency switching applications. Verify operating temperature range compatibility with the target environment.

Part Context

This part belongs to the CD214B-S2x series of glass passivated rectifier chip diodes manufactured by Bourns Inc. The series includes variants with different peak reverse voltage ratings, ranging from 200 V to 1000 V, all sharing the same 2 A forward current capability and DO-214AA compatible footprint. These components are designed for general-purpose rectification in portable and industrial electronics.

Replacement Considerations

Compatible substitutes within the same series include CD214B-S2G (400 V), CD214B-S2J (600 V), CD214B-S2K (800 V), and CD214B-S2M (1000 V). Selection depends on specific circuit voltage requirements while maintaining identical package and current ratings.
