Technical Specifications

The SUD70N03-04P features a drain-source voltage (VDS) of 30V and a continuous drain current (ID) of 70A. The on-resistance (RDS(on)) is typically 4 mΩ at a gate-source voltage of 10V. It is packaged in a PowerPAK SO-8, designed for efficient heat dissipation.

This MOSFET is specifically designed to minimize both conduction and switching losses, which are critical for achieving high efficiency in power conversion applications. The extremely low RDS(on) significantly 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 adds an extra layer of protection against voltage spikes, enhancing its reliability and robustness in demanding applications.

The SUD70N03-04P is an excellent choice for designers looking for a high-performance, energy-efficient MOSFET for power switching applications. Its combination of low on-resistance, fast switching speed, and rugged design makes it a valuable component for modern power management systems.
