Overview
The Comchip Technology CDBB140-G is a Schottky barrier rectifier featuring a 1A average forward current and a 40V maximum repetitive reverse voltage. It utilizes a compact DO-214AA (SMB) surface-mount package. The device employs silicon epitaxial planar chip technology to ensure low forward voltage drop and high efficiency. It is designed for applications requiring high surge capability and ultra-high-speed switching, providing effective overvoltage protection with minimal power loss.
Feature Summary
- Low forward voltage drop for enhanced energy efficiency
- Ultra-high-speed switching characteristics
- High surge current capability
- Guarding functionality for overvoltage protection
Applications
- Low voltage high frequency inverters
- Free wheeling diode circuits
- Polarity protection systems
Procurement Notes
Verify the specific suffix 'G' indicates RoHS compliance during procurement. Confirm the DO-214AA package dimensions match the target PCB footprint. Ensure the 40V rating aligns with the circuit's peak inverse voltage requirements. Check for lead-free certification documentation if environmental standards are mandatory for the assembly process.
Selection Notes
Select this component when a compact SMB package is required for 1A Schottky rectification at 40V. It is suitable for designs prioritizing low forward voltage drop and fast switching speeds. Consider its thermal performance in free-wheeling applications where high efficiency is critical. Verify that the operating temperature range meets the system's environmental constraints.
Part Context
This part belongs to the CDBB series of Schottky barrier rectifiers from Comchip Technology. The series is characterized by compact surface-mount packaging and high current density. It serves as a specialized diode solution for modern electronics requiring efficient power conversion and protection in limited space.
Replacement Considerations
Direct substitutes include other 1A 40V Schottky diodes in the DO-214AA package. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement maintains similar forward voltage and reverse leakage current specifications.
