Overview
The CD214B-R2800 is a glass passivated rectifier diode from the Bourns CD214B-R series, housed in a compact DO-214AA (SMB) surface-mount package. It provides a maximum average forward rectified current of 2.0 A and a repetitive peak reverse voltage of 800 V. Key electrical parameters include a maximum DC blocking voltage of 800 V, a typical junction capacitance of 25 pF at 1.0 MHz, and a maximum instantaneous forward voltage of 1.0 V at 1 A. The device supports a peak forward surge current of 65 A and operates within a temperature range of -65 °C to +175 °C.
Feature Summary
- Glass passivated chip construction for enhanced reliability
- Low reverse leakage current characteristics
- Low forward voltage drop for efficiency
- High current capability with 2.0 A average forward rating
Applications
- Rectification in portable communications equipment
- Power supply circuits in computing devices
- Video equipment power management systems
Procurement Notes
Verify component authenticity against official Bourns datasheets before integration. Confirm that the specific lot matches the required voltage and current ratings for your circuit design. Ensure handling procedures align with ESD protection standards for surface-mount components. Check for any recent product change notifications regarding packaging or material composition updates.
Selection Notes
Select this component when high reverse voltage blocking is required in space-constrained designs. The DO-214AA package offers significant PCB real estate savings compared to traditional through-hole alternatives. Consider the thermal resistance and derating curves if operating near maximum temperature limits. Ensure the application load does not exceed the 65 A surge current specification during transient events.
Part Context
This part belongs to the CD214B-R family of glass passivated rectifiers, designed for miniaturization trends in electronics. The series covers reverse voltages from 50 V to 1000 V while maintaining a consistent 2.0 A forward current rating. These diodes conform to JEDEC standards and are optimized for standard pick-and-place assembly processes due to their flat configuration.
Replacement Considerations
Compatible substitutes within the same series include CD214B-R2600 (600V) and CD214B-R1000 (1000V), provided voltage margins allow. Verify pinout compatibility and package dimensions (DO-214AA) for direct board replacement. Ensure thermal performance and leakage current specifications meet original design requirements.
