BUK9Y7R8-80E,115-VB Product details
Back to previous pageProduct introduction：
Are you designing a high power density industrial power supply or automotive-grade DC-DC module, facing the dual challenges of heat and size? Ordinary MOS tubes either lack sufficient voltage tolerance or have high conduction losses. VBsemi BUK9Y7R8-80E,115-VB offers a new solution—it integrates 80V withstand voltage, 90A high current carrying capacity, and an ultra-low on-resistance of only 6mΩ into the robust LFPAK56 package, perfectly balancing high-power conversion with compact layout.
