2SK3057-AZ-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power DC-DC converter or motor drive module, needing to handle a continuous 70A high current while also considering low loss and reliable heat dissipation? Ordinary MOSFETs either have high on-resistance or insufficient package heat dissipation. VBsemi 2SK3057-AZ-VB is designed for this—it uses a TO220F fully insulated package, offering a 60V voltage rating, 70A current capacity, and an on-resistance as low as only 10mΩ at 10V drive, allowing high power density designs to no longer worry about heating and voltage drop.
