Overview
The CD214B-S2G is a glass passivated rectifier chip diode from Bourns, housed in a compact SMB (DO-214AA) compatible package. It provides a maximum average forward current of 2 A and a repetitive peak reverse voltage of 400 V. Key electrical parameters include a maximum instantaneous forward voltage of 1.00 V at 2 A, a DC reverse current of 5 µA at rated voltage, and a typical junction capacitance of 14 pF. The device operates within a temperature range of -65 to +175 °C.
Feature Summary
- Glass passivation for enhanced stability
- Low profile SMB-compatible footprint
- High efficiency with low power loss
- Halogen-free and RoHS compliant construction
Applications
- Switch Mode Power Supplies
- DC/DC Converters
- Portable equipment batteries
- Telecommunications
- High frequency rectification
Procurement Notes
Verify the specific part number against the official Bourns datasheet to ensure correct voltage rating and package compatibility. Confirm that the procurement specifications align with the absolute maximum ratings and thermal resistance values provided in the technical documentation. Ensure compliance with environmental directives such as RoHS and halogen-free requirements before finalizing orders.
Selection Notes
Select this component for applications requiring a 400 V reverse voltage rating and 2 A continuous forward current capability. Consider the SMB package size for space-constrained PCB layouts. Evaluate the thermal management requirements based on the specified junction-to-ambient thermal resistance. Ensure the operating environment stays within the stated temperature limits for reliable performance.
Part Context
This component belongs to the CD214B-S2x series of glass passivated rectifier diodes manufactured by Bourns Inc. The series offers various voltage ratings ranging from 200 V to 1000 V, all sharing the same 2 A current capacity and SMB package format. These diodes are designed to meet the demands of modern electronics for smaller components without sacrificing performance.
Replacement Considerations
Compatible substitutes include other SMB-packaged rectifiers with matching 400 V reverse voltage and 2 A forward current ratings. Verify pinout compatibility and thermal characteristics when replacing. Ensure any alternative component meets the same RoHS and halogen-free standards required by the original design specifications.
