Overview
The CD214B-R21000 is a glass passivated rectifier diode from Bourns, designed for surface mount applications in the compact DO-214AA (SMB) package. It features a maximum average forward rectified current of 2.0 A and a maximum repetitive peak reverse voltage of 1000 V. The device exhibits low reverse leakage current and low forward voltage drop, with a typical junction capacitance of 25 pF. It operates within a temperature range of -65 °C to +175 °C and supports a peak forward surge current of 65 A.
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 rectified current
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 documentation before integration. Confirm RoHS compliance status and check for any recent product discontinuation notices or engineering change orders. Ensure storage conditions align with manufacturer specifications to maintain device integrity prior to assembly.
Selection Notes
Select this component for designs requiring high voltage blocking capabilities in a small surface mount footprint. Consider the thermal resistance and derating curves when determining heat dissipation requirements. Verify compatibility with standard pick-and-place equipment due to the flat SMB package configuration.
Part Context
This part belongs to the CD214B-R series of glass passivated rectifiers offered by Bourns. The series provides various voltage ratings from 50 V to 1000 V within the same DO-214AA package format. These diodes are engineered to save PCB real estate compared to traditional through-hole alternatives while maintaining robust electrical performance.
Replacement Considerations
Direct substitutes include other CD214B-R series variants with matching voltage ratings, such as CD214B-R800 or CD214B-R1000, if lower voltage ratings are acceptable. Cross-brand replacements must match the DO-214AA package, 2.0 A current rating, and 1000 V reverse voltage specifications.
