Equivalent & Substitute Parts for IXFT24N50

Part Overview

The IXFT24N50 is an N-Channel power MOSFET, part of the IXYS HiPerFET™ series, designed for high voltage and high current applications. It offers a 500V drain-to-source voltage and continuous drain current of 24A, rated for up to 300W (Tc) in a surface mount TO-268AA package. As this model is now classified as Obsolete, sourcing equivalent and substitute parts with compatible electrical and mechanical parameters within the MOSFET category is necessary for design continuity and maintenance.
