IXFK48N40 MOSFET: Low RDS(on) & Tough TO-264 Package

High conduction losses generate severe thermal stress in high-power switching circuits. Inefficient power transistors waste energy as excessive heat, forcing engineers to use oversized heatsinks and active cooling fans. The IXFK48N40 N-channel power MOSFET fixes energy loss by combining high current capacity with ultra-low on-resistance. Manufactured by IXYS, the IXFK48N40 handles a 400V drain-source breakdown voltage with a continuous drain current of 48A. Housed in a heavy-duty TO-264 package, its rugged international footprint provides superior power dissipation and thermal transfer to external heatsinks. Fast switching speeds reduce switching losses, while low gate charge allows simple drive circuit integration across high-frequency power converters. Power systems designers choose this discrete MOSFET for switch-mode power supplies, motor drives, and DC-DC converters where high efficiency is required. Stop letting thermal inefficiency drain system performance. Build your high-voltage power conversion boards with switching transistors engineered for low-loss conduction.
