2SK3432-AZ-VB Product details
Back to previous pageProduct introduction：
Are you designing a high-power DC-DC converter or a motor drive circuit requiring continuous high-current output? Ordinary MOSFETs either suffer from high conduction losses, with heat sinks taking up most of the PCB, or lack sufficient withstand voltage, becoming precarious during voltage fluctuations. VBsemi 2SK3432-AZ-VB provides the ideal solution—it adopts a large TO263 package, integrating 40V withstand voltage, 100A current-carrying capacity, and an ultra-low on-resistance of 5mΩ, allowing high-power designs to balance efficiency and reliability.
