CDBQR0140R

Overview

The CDBQR0140R is a surface-mount Schottky barrier diode manufactured by Comchip Technology. It features an average forward rectified current of 100 mA and a repetitive peak reverse voltage rating of 45 V, with a standard reverse voltage of 40 V. The device utilizes majority carrier conduction to achieve low forward voltage characteristics. It is housed in an extremely thin, leadless 0402 (SOD-923F) package designed for small surface mounting applications.

Feature Summary

• Low reverse leakage current for improved efficiency
• Majority carrier conduction mechanism
• Extremely thin and leadless package design

Applications

• Small surface-mounted electronic circuits
