DB4-AP

DIACs, SIDACs Overview

The MCC DB4-AP is a single-phase bridge rectifier manufactured by Micro Commercial Components. It utilizes glass passivated junction technology for enhanced reliability and stability under varying thermal conditions. The device is designed for general-purpose AC-to-DC conversion applications requiring robust performance in compact form factors. Key electrical specifications include a maximum repetitive peak reverse voltage of 400V and an average forward rectified current rating of 1A. The component features a low forward voltage drop to minimize power loss and heat generation during operation. It is housed in a DO-201AD (DO-15) axial leaded package, suitable for through-hole mounting on printed circuit boards.
