Procurement Notes
Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compliance with RoHS directives as indicated in current datasheets. Cross-reference part numbers carefully, as variations such as HF or LR may denote specific material or performance attributes defined solely by the manufacturer's release notes.
Selection Notes
Select this component for applications requiring efficient rectification in compact surface-mount designs. The DO-214AC package offers robust thermal performance suitable for high-current scenarios. Evaluate the 100 V reverse voltage rating against peak inverse voltages in the target circuit to ensure adequate safety margins under transient conditions.
Part Context
This device belongs to the CDBA3100 series of Schottky barrier rectifiers from Comchip Technology. The series is characterized by low forward voltage and low reverse leakage, designed for general-purpose rectification in space-constrained electronic assemblies. The LR suffix typically denotes specific manufacturing lot or environmental compliance attributes defined by the producer.
Replacement Considerations
Compatible substitutes include the CDBA3100-G and CDBA3100-HF from Comchip Technology, which share similar 100 V/3A ratings and DO-214AC packaging. Verify pinout compatibility and thermal characteristics before substitution.
