Overview
The CD214B-S3D is a glass passivated rectifier chip diode from the CD214B-S3x series, manufactured by Bourns Inc. It features a DO-214AA (SMB) compatible package and supports a maximum average forward current of 3 A with a peak forward surge current of 96 A. The device provides a maximum repetitive peak reverse voltage of 200 V and exhibits a typical junction capacitance of 23 pF at 4 V reverse bias. Electrical characteristics include a maximum instantaneous forward voltage of 1.00 V at 3 A and a DC reverse current of 5 µA at rated voltage. Operating and storage temperature ranges extend from -65 °C to +175 °C.

Procurement Notes
Verify the specific part number suffix against official Bourns documentation to confirm voltage ratings and package compatibility. Confirm compliance requirements such as RoHS and halogen-free status prior to procurement. Check for any regional restrictions or supply chain notifications related to this component series before finalizing orders.
Selection Notes
Select the CD214B-S3D when a 200 V repetitive peak reverse voltage rating is required alongside a 3 A continuous forward current capability. Ensure the application environment remains within the specified -65 °C to +175 °C operating temperature range. Consider the SMB package dimensions and thermal resistance values for adequate heat dissipation in the target circuit design.
Part Context
This component belongs to the CD214B-S3x series of glass passivated rectifier chip diodes offered by Bourns. The series covers various voltage ratings from 200 V to 1000 V while maintaining a consistent 3 A forward current capacity. These devices are designed for surface mount applications requiring high efficiency and low power loss in portable and industrial electronics.
Replacement Considerations
Compatible substitutes within the same series include CD214B-S3G (400 V), CD214B-S3J (600 V), CD214B-S3K (800 V), and CD214B-S3M (1000 V). Verify that the alternative part's voltage rating meets or exceeds the original circuit requirements.
