Product introduction：
**
W203-VB is a bipolar N+N-Channel MOSFET in SOP8 package, designed for low voltage, high efficiency power management and switch control applications. The device has a maximum drain-source voltage (VDS) of 30V, a maximum gate-source voltage (VGS) of ±20V, and can provide a low on-resistance (RDS(ON)), which is 26mΩ (VGS=4.5V) and 22mΩ (VGS=10V). Its maximum drain current is 6.8A and 6.0A (two channels), with high current carrying capacity and good thermal stability. W203-VB uses Trench technology and can provide excellent performance in multiple low-power power and switching applications. It is widely used in power conversion, smart devices and battery management.
