IRF4905 PDF Specs and Replacement
The IRF4905 is a rugged P-channel power MOSFET designed for high-current, low-voltage switching applications. Built with advanced MOSFET technology, it features a low on-resistance of approximately 0.02Ohm at Vgs=10V, enabling efficient power delivery with minimal conduction losses. Its drain-source voltage rating is 55V, making it suitable for automotive, DC motor control, battery-powered systems. The device supports continuous drain currents up to 74A when properly heat-sunk and offers fast switching characteristics due to its low gate charge. This reduces switching losses and improves efficiency in high-frequency circuits. The TO220 package ensures good thermal performance and ease of integration. As a high-power P-channel option, the IRF4905 remains a reliable choice for reverse-polarity protection, high-side switching, robust power management designs.
