Overview
The CDBA140L-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 peak reverse voltage of 40V with an average forward rectified current rating of 1A. The device utilizes silicon epitaxial planar chip technology to achieve ultra-high-speed switching capabilities. Key electrical characteristics include a low forward voltage drop and minimal reverse leakage current, ensuring high efficiency and low power loss in rectification circuits.
Feature Summary
- Low forward voltage drop for optimized power efficiency
- Ultra-high-speed switching capability
- Guardring structure for enhanced overvoltage protection
Applications
- Low profile surface mount applications requiring board space optimization
- High frequency rectification circuits
- DC-DC converter output stages
Procurement Notes
Verify the specific suffix 'HF' indicates halogen-free compliance as per manufacturer specifications. Confirm the package designation matches DO-214AC (SMA) requirements for your PCB footprint. Ensure thermal management aligns with the device's operating temperature range and derating curves for capacitive loads.
Selection Notes
Select this component when a 40V reverse voltage rating and 1A continuous current are sufficient for the circuit design. The SMA package is suitable for standard surface-mount assembly processes. Consider the low forward voltage characteristic if minimizing conduction losses is a primary design constraint compared to standard PN junction diodes.
Part Context
This part belongs to Comchip Technology's SMD Schottky Barrier Rectifier series, which emphasizes low profile and high efficiency. The product line targets applications where space constraints and switching speed are critical factors. The CDBA140L-HF represents a specific voltage and current configuration within this broader family of semiconductor devices.
Replacement Considerations
Cross-reference with other 1A 40V SMA Schottky diodes from different manufacturers. Verify pinout compatibility and thermal resistance values before substitution. Ensure the alternative component meets the same RoHS and halogen-free requirements if applicable.
