IRFZ46ZSPBF-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power DC-DC converter or motor drive module, needing to handle both 60V bus voltage and maintain cool operation under 75A high current? Ordinary MOSFETs either have high on-resistance or limited package heat dissipation. VBsemi IRFZ46ZSPBF-VB is built for this—it integrates 60V withstand voltage, 75A current carrying capacity, and an on-resistance of only 11mΩ into the TO263 industry-standard package, combined with Trench trench technology, making high-power power supply designs both efficient and reliable.
