IRF4905TRLPBF – INFINEON

The Infineon IRF4905TRLPBF is a 55V P-Channel HEXFET Power MOSFET optimized for high-side load switching and battery management applications where efficiency and thermal performance are critical. It boasts a low on-resistance (RDS(on)) of 20 mΩ at VGS = -10V, facilitating minimal power dissipation. This MOSFET is capable of handling a continuous drain current (ID) of 74A and pulsed drain current of up to 240A. The IRF4905TRLPBF is supplied in a standard through-hole TO-220 package, allowing for robust mechanical mounting and effective heat sinking. Its operating temperature range spans from –55°C to 175°C, ensuring reliable operation in demanding environments. The device’s low gate charge simplifies gate drive circuitry and minimizes switching losses, making it ideal for DC-DC converters and motor control. The “TRLPBF” suffix indicates tape and reel packaging and lead-free termination.
