Technical Specifications

The SUD50NP04-73P typically features a drain-source voltage (VDS) of 40V and a continuous drain current (ID) of up to 50A, depending on the operating conditions. The on-resistance (RDS(on)) is very low, typically around 7.3 mΩ at a gate-source voltage of 10V. The gate charge (Qg) is also low, contributing to reduced switching losses. The device is packaged in a PowerPAK SO-8, designed for efficient heat dissipation.

This MOSFET is specifically designed to minimize conduction and switching losses, which are critical for achieving high efficiency in power conversion applications. The low RDS(on) reduces the power dissipated as heat during conduction, while the fast switching speed and low gate charge minimize losses during switching transitions. The avalanche rating ensures that the device can withstand transient voltage spikes, enhancing its reliability and robustness in demanding applications.

The SUD50NP04-73P is an excellent choice for designers seeking a high-performance, energy-efficient MOSFET for a variety of power switching applications. Its combination of low on-resistance, fast switching speed, and rugged design makes it a valuable component in modern power management systems.
