Overview
The CDBA280-G is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a single diode configuration within a DO-214AB (SMA) package. The device is rated for a maximum average forward rectified current of 2 Amperes and a repetitive peak reverse voltage of 80 Volts. Key electrical characteristics include a low forward voltage drop of 500 millivolts at the rated current and a maximum reverse leakage current of 5 microamperes. The component supports a forward surge current of 60 Amperes and operates reliably at junction temperatures up to +175°C, ensuring robust performance in high-temperature environments.
Feature Summary
- Utilizes Schottky barrier technology to achieve low forward voltage drop and minimal power loss during conduction.
- Engineered with a plastic encapsulate compliant with UL flammability standards for enhanced safety.
- Designed for high thermal stability, supporting operation at elevated junction temperatures up to +175°C.
Applications
- DC-to-DC converters
- Power supply units
- Adapters
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging specifications. Ensure that the procurement documentation explicitly references the CDBA280-G part number to avoid confusion with similar SMA-rated devices. Confirm RoHS compliance status through the latest certified product list provided by Comchip Technology prior to finalizing acquisition.
Selection Notes
Select this component when designing circuits requiring efficient rectification with low forward voltage characteristics in a compact surface-mount form factor. The 80V rating makes it suitable for intermediate voltage levels in power conversion stages. Consider the 2A current capacity and thermal limits when determining heat dissipation requirements for the printed circuit board layout.
