Overview
The CD214B-S3M is a glass passivated rectifier chip diode from the CD214B-S3x series, manufactured by Bourns Inc. It operates in a compact SMB/DO-214AA compatible package with a maximum average forward current of 3 A and a maximum repetitive peak reverse voltage of 1000 V. The device supports an operating junction temperature range from -65 °C to +175 °C. 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. Typical junction capacitance is 23 pF at 4 V reverse bias.

Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS and halogen-free status against latest datasheet revisions. Ensure storage conditions maintain moisture sensitivity level 1 integrity. Validate marking codes match specific ordering suffixes before assembly.
Selection Notes
Select this component for high-voltage rectification requiring robust thermal performance. The 1000 V rating suits applications demanding significant reverse voltage isolation. Verify PCB pad layouts align with recommended dimensions for reliable soldering. Consider thermal resistance values when designing heat dissipation strategies.
Part Context
This part belongs to the CD214B-S3x series of rectifier chip diodes. The series offers various voltage ratings ranging from 200 V to 1000 V within the same physical package. All variants share identical current handling capabilities and packaging specifications.
Replacement Considerations
Direct substitutes include other CD214B-S3x variants such as CD214B-S3D, S3G, S3J, or S3K if lower voltage ratings are acceptable. Cross-brand replacements require matching DO-214AA footprint and electrical parameters.
