Overview
The CDBB240-G is a Schottky barrier rectifier manufactured by Comchip Technology, designed for surface-mount applications. It features a single diode configuration within the DO-214AA (SMB) package. The device utilizes silicon epitaxial planar chips with metal-silicon junctions to ensure reliable operation. Key electrical characteristics include a maximum repetitive reverse voltage of 40 V and an average forward rectified current of 2 A. The component exhibits a low forward voltage drop and high surge capability, making it suitable for efficient power conversion in compact electronic designs.
Feature Summary
- Low forward voltage drop for enhanced efficiency
- High surge current capability for robust performance
- Ultra-fast switching characteristics
- Guarding against overvoltage conditions
Applications
- Polarity protection circuits
- Free-wheeling diodes in low voltage systems
- General purpose rectification in consumer electronics
Procurement Notes
Verify the specific suffix 'G' corresponds to halogen-free compliance when sourcing. Confirm the package type matches the required PCB footprint. Ensure the manufacturer documentation aligns with the requested RoHS standards. Cross-reference the part number with official distributor catalogs to avoid counterfeit components. Validate thermal management requirements based on the specified power dissipation limits.
Selection Notes
Select this component for applications requiring a 40 V reverse voltage rating and 2 A continuous current handling. The SMB package offers a balance between current capacity and board space. Consider the low forward voltage characteristic for minimizing power loss in low-voltage DC circuits. Evaluate the operating temperature range to ensure compatibility with the environmental conditions of the target assembly.
Part Context
This component belongs to the CDBB series of SMD Schottky Barrier Rectifiers from Comchip Technology. The series is characterized by low leakage current and fast recovery times. It is engineered for use in general-purpose rectification where size constraints are critical. The DO-214AA package provides standardized mounting dimensions compatible with automated assembly processes.
Replacement Considerations
Compatible substitutes include the CDBB240-HF variant from the same manufacturer. Other equivalents may be found within the SMB package Schottky rectifier category, provided they meet or exceed the 40 V and 2 A specifications.
