IRFZ44NSTRRPBF-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power DC-DC converter or motor drive module that needs to handle tens of amperes of current while controlling conduction losses and temperature rise? Ordinary MOS tubes either lack voltage tolerance or have high on-resistance, making thermal design challenging. VBsemi IRFZ44NSTRRPBF-VB is built for this—it combines 60V voltage tolerance, 75A current capacity, and an on-resistance as low as 11mΩ in a TO263 package, allowing high-power density design without compromise.
