Procurement Notes
This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify end-of-life status before finalizing designs. Tariff implications may apply if shipping to specific regions. Ensure alternative sourcing strategies are in place due to limited future availability.
Selection Notes
Select this part for applications demanding robust mechanical integrity and high-temperature performance. The SMC package offers superior heat dissipation compared to smaller footprints. Consider the 100 V rating and 3 A current capability against circuit requirements. Verify compatibility with automated surface-mount assembly processes given the package type.
Part Context
Comchip Technology specializes in surface-mount discrete semiconductors, including Schottky diodes and rectifiers. The CDBC series focuses on ruggedized packages for industrial use. This model represents a high-current variant within their Schottky portfolio, emphasizing durability and thermal efficiency for demanding electronic systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolescence status, engineering change orders should evaluate equivalent Schottky rectifiers in the DO-214AB package with matching 100 V and 3 A ratings.
