2SK3481(0)-Z-E1-AZ-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power-density industrial power supply or motor drive module with limited board space, yet it must withstand current surges of up to 45A. Ordinary MOSFETs either suffer from excessive conduction losses or have bulky packages that are difficult to layout. VBsemi 2SK3481(0)-Z-E1-AZ-VB is designed for this purpose — it integrates 100V withstand voltage, 45A current-carrying capacity, and an on-resistance as low as 30mΩ into a TO263 (D2PAK) package, allowing high-power designs to both "handle the load" and "dissipate the heat."
