STU434S-VB Product details
Back to previous pageProduct introduction：
The STU434S-VB is a high-current, low-loss N-channel MOSFET in a TO252 package. It features a 40V drain-source voltage rating and an 85A continuous drain current capability. Leveraging Trench technology, it achieves an ultra-low on-resistance of 5mΩ (at 10V drive), resulting in minimal heat generation and high efficiency. The gate drive is flexible with a ±20V wide range, making it suitable for various low-voltage power control applications.
