International Rectifier introduced the IRF4000, an integrated MOSFET solution for Power over Ethernet applications. The IRF4000 combines four MOSFETs into a single package, reducing the footprint by up to 80% compared to individual MOSFET packages. The reduced part count and space savings simplify manufacturing for PoE systems like Ethernet switches. The IRF4000 is rated for 100V and complies with IEEE 802.3af PoE specifications, delivering up to 15W per port in a reliable and thermally optimized package.
