BUK7Y12-55B,115-VB Product details
Back to previous pageProduct introduction：
You are designing a high-power-density DC-DC converter that must withstand bus voltages up to 60V while minimizing switching losses and heat generation. Ordinary MOSFETs either lack sufficient voltage tolerance or have high on-resistance, leading to increasingly bulky heatsinks. The VBsemi BUK7Y12-55B,115-VB is designed for this—it integrates 60V withstand voltage, 64A current capacity, and an ultra-low on-resistance of only 6.2mΩ into the LFPAK56 package, allowing high-power power supply designs to no longer worry about heat dissipation and space constraints.
