IRF7403 MOSFET (400V, 10A)

Overview

The IRF7403 is a compact N-Channel Power MOSFET in an SO-8 (SMD) package, engineered for high-speed switching and efficient power management. With a drain-to-source voltage of 400V and a continuous drain current of 10A, this MOSFET is a robust choice for a wide range of power electronics applications. Its low on-resistance (RDS(on)) minimizes power loss and heat generation, while its logic-level gate drive capability makes it directly compatible with microcontrollers like Arduino, ESP32, STM32, and Raspberry Pi. Whether you're building a DC-DC converter, motor driver, or battery management system, the IRF7403 delivers reliable performance in a space-saving SMD form factor.
