BUK9Y12-80E,115-VB Product details
Back to previous pageProduct introduction：
You are designing a high power density industrial power module that must withstand current surges up to 90A while achieving efficient heat dissipation on a limited PCB area. Ordinary MOS tubes either lack sufficient voltage tolerance or have excessive conduction losses. VBsemi BUK9Y12-80E,115-VB is born for this—it integrates 80V withstand voltage, 90A current carrying capacity, and an ultra-low on-resistance of 6mΩ into the compact LFPAK56 package, enabling high-power conversion system designs to excel without compromising on heat dissipation and space constraints.
