Overview
The CDBA120SL-HF is a surface mount Schottky barrier rectifier from Comchip Technology, housed in the DO-214AC (SMA) package. It features a maximum average forward rectified current of 1.0 A and a maximum repetitive peak reverse voltage of 20 V. The device exhibits a maximum instantaneous forward voltage of 0.31 V at 1.0 A. Electrical characteristics include a maximum DC reverse current of 1.0 mA at 25°C and 35 mA at 80°C when rated at the DC blocking voltage. The component supports an operating temperature range from -50°C to +125°C and a storage temperature range from -50°C to +125°C.
Feature Summary
- Super low forward voltage drop for high efficiency
- Built-in strain relief for mechanical stability
- Metallurgically bonded construction with UL 94V-0 flame retardant epoxy
Applications
- Surface mount applications requiring compact footprint
- Pick and place automated assembly processes
- Low voltage power supply rectification
Procurement Notes
Verify the specific part number suffix against official manufacturer documentation to confirm electrical ratings and package type. Ensure compliance with RoHS directives if required by the application environment. Cross-reference datasheet revision numbers to validate thermal resistance and surge current specifications before finalizing procurement orders.
Selection Notes
Select this component for designs prioritizing low forward voltage drop within the SMA package constraint. Evaluate the 1.0 A continuous current rating against peak load requirements. Consider the 20 V reverse voltage limit for input protection or rectification circuits. Verify thermal management capabilities given the junction temperature limits and derating curves provided in the datasheet.
Part Context
This device belongs to the CDBA120L through CDBA140SL series of SMD Schottky Barrier Rectifiers manufactured by Comchip Technology. The series offers various voltage ratings from 20 V to 40 V while maintaining a consistent 1.0 A forward current capability across different package variants like the DO-214AC.
Replacement Considerations
Compatible substitutes within the same series include CDBA120L and CDBA120LL, which share the 20 V rating but may differ in forward voltage characteristics. For higher voltage requirements, the CDBA140SL variant provides a 40 V rating with identical current handling and package dimensions.
