Product introduction：
**VB7430 Product Introduction**
VB7430 is a high-performance N-channel MOSFET in a small SOT23-6 package, designed for efficient power management and high-speed switching applications. The device has a drain-source withstand voltage (VDSS) of 40V, a gate drive voltage range of ±20V, and can be turned on at a minimum gate voltage of 1.65V. Its on-resistance (RDS(on)) is as low as 25mΩ (maximum), supporting a continuous drain current of up to 6A. VB7430 uses advanced Trench technology, which enables it to excel in the field of low-power, high-efficiency switching and power conversion. This MOSFET is suitable for a variety of applications such as load switches, DC-DC converters, motor drives, LED drives, and lithium battery protection.
