BUK7Y28-75B,115-VB Product details
Back to previous pageProduct introduction：
VBsemi BUK7Y28-75B,115-VB is a Single N-channel field-effect transistor using Trench technology, designed for medium-to-high voltage power conversion and high current load control scenarios. Its LFPAK56 package offers excellent heat dissipation and low parasitic parameters, suitable for high-density power PCB layouts. The device provides stable switching characteristics within an 80V drain-source voltage range, with an on-resistance as low as 6mΩ (driven at 10V), supporting a continuous drain current of up to 90A. The gate drive is compatible with 4.5V logic levels, enabling flexible system design.
