Overview
The CD214B-F3400 is a surface mount fast response rectifier manufactured by Bourns Inc. It features a glass-passivated silicon junction in a compact DO-214AA (SMB) package. The device supports a maximum average forward rectified current of 3.0 A and a maximum repetitive peak reverse voltage of 400 V. Key electrical characteristics include a typical junction capacitance of 10 pF, a maximum instantaneous forward voltage of 1.7 V at 1 A, and a maximum reverse recovery time of 35 ns. It operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Glass passivation provides mechanical strength and stability against environmental variations.
- Fast response design ensures low reverse recovery time for high-speed switching applications.
- Compact SMB package minimizes PCB real estate usage compared to larger competitors.
Applications
- Portable communications equipment
- Computing systems
- Video equipment
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status as the datasheet indicates lead-free versions are available. Check for obsolescence notices, as this series may be discontinued or superseded by newer models like the CD214B-FS3x. Ensure storage conditions align with specified temperature ranges to maintain performance integrity.
Selection Notes
Select this component when a 400 V reverse voltage rating and 3 A continuous current capacity are required in a small form factor. Consider the 35 ns reverse recovery time for high-frequency circuits. Evaluate thermal resistance requirements, noting the specific pad layout recommendations for optimal heat dissipation. Verify compatibility with standard pick-and-place equipment due to the flat configuration.
Part Context
This part belongs to the CD214B-F350~F3600 series of surface mount fast response rectifiers. These devices are designed for general-purpose rectification in space-constrained electronics. The series offers various voltage ratings from 50 V to 600 V while maintaining consistent current handling capabilities across the lineup.
Replacement Considerations
The datasheet explicitly recommends the CD214B-FS3x Series as the replacement for this model. Designers should verify pinout compatibility and electrical parameter equivalence before substituting components in existing designs.
