CDBA140LL-G

Overview

The CDBA140LL-G is a Schottky Barrier Rectifier manufactured by Comchip Technology, designed for low-profile surface-mounted applications to optimize board space. It utilizes a silicon epitaxial planar chip with a metal-silicon junction, offering ultra-high-speed switching and high surge capability. The device features low forward voltage drop, high efficiency, and excellent power dissipation which contributes to better reverse leakage current and thermal resistance. It provides guarding for overvoltage protection and meets environmental standards including RoHS compliance.

Feature Summary

• Ultra-high-speed switching capability
• Low profile package design
• High surge current capability
• Guarding for overvoltage protection

Applications

• Low profile surface mounted applications
• Power supply circuits requiring high efficiency
• Overvoltage protection circuits

Procurement Notes

Verify the specific suffix (G vs HF) against the manufacturer's datasheet to confirm exact environmental compliance status, as suffixes may indicate variations in halogen-free or lead-free specifications. Ensure the DO-214AC (SMA) package footprint matches the target PCB layout. Confirm that the 40V reverse voltage rating is sufficient for the peak inverse voltage in the intended circuit application.

Selection Notes

Select this component when a low-profile SMD Schottky rectifier is required for space-constrained designs. The CDBA140LL-G offers a balance of high current handling and fast switching speeds suitable for general-purpose rectification. Consider the thermal resistance characteristics if operating in high-temperature environments, as the batch process design aims to improve heat dissipation compared to standard packages.
