CEM3178-VB Product details
Back to previous pageProduct introduction：
VBsemi CEM3178-VB is a dual N+N channel field-effect transistor using Trench technology, designed for medium-to-low voltage power conversion and precision control scenarios. Its SOP8 package integrates dual channels within a compact volume, balancing thermal performance and layout flexibility, suitable for high-density PCB design. The device provides stable switching characteristics within a 30V drain-source voltage range, with an ultra-low on-resistance of 16mΩ (VGS=10V), supporting 8.5A continuous drain current. The gate drive is compatible with common 4.5V logic levels, facilitating system integration.
