Overview
The CDBA120LL-HF is a surface-mount Schottky Barrier Rectifier manufactured by Comchip Technology. It features a single diode configuration with a maximum average forward rectified current of 1 A and a maximum repetitive peak reverse voltage of 20 V. The device utilizes a DO-214AC (SMA) package, designed for low-profile applications. Key electrical characteristics include ultra-low forward voltage drop and high efficiency, making it suitable for high-speed switching and power conservation in compact electronic designs.
Feature Summary
- Ultra-low forward voltage drop for enhanced energy efficiency
- Low profile surface mount construction for space-constrained PCBs
- High surge current capability for robust circuit protection
- Lead-free construction compliant with environmental standards
Applications
- Low voltage DC-DC converters
- Power supply freewheeling diodes
- Reverse polarity protection circuits
- Clamping and snubber applications
Procurement Notes
Verify the specific suffix 'HF' confirms lead-free status as per manufacturer specifications. Ensure the DO-214AC package footprint matches your PCB design constraints. Confirm that the 20V reverse voltage rating provides adequate margin for your operating conditions. Check for RoHS compliance documentation if required by your assembly standards.
Selection Notes
Select this component when a low forward voltage drop is critical for system efficiency at 1 A currents. The 20V rating suits low-voltage logic and battery-powered systems. Consider the SMA package size relative to available board space. Compare thermal resistance requirements against ambient operating temperatures to ensure reliable junction temperature management under load.
Part Context
This part belongs to Comchip Technology's CDBA series of Schottky barrier rectifiers. The series is characterized by ultra-low forward voltage performance and high reliability. These devices are engineered for general-purpose rectification in modern electronics, offering a balance of speed, efficiency, and compact form factor suitable for consumer and industrial applications.
Replacement Considerations
Equivalent parts must match the 1 A current, 20 V reverse voltage, and DO-214AC package. Verify forward voltage and reverse leakage specifications align with original design requirements. Ensure thermal characteristics support the intended application environment without derating issues.
