TUAR4DH

Single Diodes Overview

The TUAR4DH is a fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a 200V repetitive peak reverse voltage rating and a 4A average forward rectified current capability. The device utilizes the SMPC surface-mount package, designated as SMPC4.6U in official documentation. Key electrical specifications include a maximum forward voltage drop of 1.3V at rated current and a typical reverse recovery time of 150ns. These parameters define its performance envelope for high-speed switching applications.
