BUK9Y43-60E,115-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power-density DC-DC converter or motor drive module with limited PCB area, yet needing to output tens of amperes of continuous current. Ordinary MOSFETs either have high conduction losses or are too large with difficult heat dissipation. The VBsemi BUK9Y43-60E,115-VB is designed for this—it integrates 60V withstand voltage, 64A current capacity, and a low on-resistance of 6.2mΩ into the compact LFPAK56 package, enabling high-power power supply designs to easily achieve high efficiency and low temperature rise in limited space.
