BUK9R4R5-40HJ-VB Product details

Product introduction:

BUK9R4R5-40HJ-VB is a high-current, low-loss N-channel MOSFET, packaged in DFN8(5X6), with a 40V withstand voltage and 70A current carrying capacity. With Trench technology, the on-resistance is as low as 4.7mΩ at 10V drive and only 6mΩ at 4.5V drive, resulting in low heat generation and high efficiency. The gate drive is flexible, with a wide ±20V range, adapting to various low-voltage control and power conversion scenarios.
