onsemi MURD620CT Dual Diode Rectifier: Features and Applications

The onsemi MURD620CT is a high-performance dual diode rectifier designed for high-efficiency power conversion applications. This rectifier features two ultra-fast recovery diodes co-packaged within a TO-252 (DPAK) surface-mount package, providing a compact and robust solution for modern electronic circuits. With its ultra-fast recovery time and low forward voltage drop, the device minimizes switching losses and enhances overall system efficiency, making it particularly suitable for high-frequency operations.

Key features of the MURD620CT include a repetitive peak reverse voltage of 200V, an average forward rectified current of 4A per diode, and a surge current capability of 150A. Its ultra-fast recovery time (typically 35ns) ensures reduced reverse recovery losses, which is critical in minimizing electromagnetic interference (EMI) and improving thermal performance. The device is also characterized by its high junction temperature capability (up to 175°C), allowing it to operate reliably in demanding environments.

The MURD620CT is widely used in applications such as switch-mode power supplies (SMPS), freewheeling diodes, polarity protection circuits, and high-frequency inverters. It is also ideal for use in automotive systems, industrial motor controls, and renewable energy systems where efficiency, compactness, and reliability are paramount. Its dual-diode configuration simplifies board layout and reduces component count, contributing to lower assembly costs and higher power density designs.
