Overview
The CDBA140-HF is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface mount applications. It features a DO-214AC (SMA) package and provides a maximum repetitive reverse voltage of 40 V with an average forward current rating of 1 A. The device exhibits a low forward voltage drop of 500 mV at the rated current and supports a high surge current capability of 30 A. Operating temperatures range from -55°C to +150°C junction temperature, ensuring reliability in demanding environments.
Feature Summary
- Low forward voltage drop for high efficiency
- Guardring structure for overvoltage protection
- Ultra-high-speed switching capability
- Silicon epitaxial planar chip construction
Applications
- Low profile surface mount applications
- DC-DC converters
- Power supply circuits requiring high efficiency
Procurement Notes
Verify the specific datasheet version when sourcing, as electrical characteristics such as reverse leakage current may vary between manufacturer revisions. Confirm that the DO-214AC package dimensions match your PCB footprint requirements. Ensure compliance with RoHS standards if required by your assembly specifications. Cross-reference part numbers carefully to distinguish between similar SMA variants.
Selection Notes
Select this component when a compact SMA package is required alongside moderate current handling capabilities. The 40 V rating suits low-voltage DC bus applications. Consider the 30 A surge rating for inrush current scenarios. Compare against other Schottky diodes in the same package family based on specific forward voltage and leakage current tolerances for optimal circuit performance.
Part Context
This part belongs to Comchip Technology's SMD Schottky Barrier Rectifier series, which includes various voltage ratings within the SMA package. The product line emphasizes low power loss and high current capability for space-constrained designs. Similar parts in the series offer different reverse voltage options while maintaining consistent thermal and mechanical characteristics.
Replacement Considerations
Direct substitutes include other 40 V, 1 A Schottky diodes in the DO-214AC package. Verify pinout compatibility and thermal resistance values before substitution. Ensure replacement components meet or exceed the original surge current and operating temperature specifications.
