Overview
The CD214B-R2400 is a glass passivated rectifier diode manufactured by Bourns Inc. It operates within a junction temperature range of -65 °C to +175 °C and features a maximum repetitive peak reverse voltage (VRRM) of 400 V. The device supports a maximum average forward rectified current of 2.0 A with a typical instantaneous forward voltage of 1.0 V at 1 A. Key electrical parameters include a DC reverse current of 5.0 µA at 25 °C, a peak forward surge current of 65 A, and a typical junction capacitance of 25 pF.
Feature Summary
- Glass passivated chip construction for enhanced reliability
- Low reverse leakage current characteristics
- Low forward voltage drop for efficiency
- High current capability in compact SMB/DO-214AA package
Applications
- Rectification in portable communications equipment
- Power supply circuits in computing devices

Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm current availability status. Check for any product discontinuation notifications or engineering change notices that may affect long-term supply. Ensure compliance with relevant environmental directives such as RoHS requirements before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring a 400 V reverse voltage rating and 2.0 A continuous forward current. The DO-214AA package is suitable for surface mount assembly using standard pick-and-place equipment. Consider the thermal resistance and derating curves when designing for high ambient temperatures or limited PCB copper area.
Part Context
This component belongs to the CD214B-R series of glass passivated rectifiers from Bourns. The series offers various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 2.0 A current capacity. These diodes are designed to save PCB real estate compared to larger competitive parts, fitting into the compact SMB form factor.
Replacement Considerations
Compatible substitutes must match the 400 V reverse voltage, 2.0 A forward current, and DO-214AA package. Verify equivalent forward voltage and reverse leakage specifications to ensure circuit performance remains unchanged.
