Product Introduction
**TD381BA-VB** is a unipolar N-channel MOSFET in TO252 package, designed with Trench technology. It has extremely low on-resistance (RDS(ON)) and high current carrying capacity, and is particularly suitable for high-efficiency power supply and load switching applications. The maximum drain-source voltage (VDS) of this MOSFET is 30V, the maximum gate-source voltage (VGS) is ±20V, the threshold voltage (Vth) is 1.7V, and it has a very low on-resistance of 5mΩ at VGS=10V and 6mΩ at VGS=4.5V. This enables it to operate at low voltage and high current load, reducing energy loss and improving system efficiency. TD381BA-VB is particularly suitable for applications such as high-frequency, high-power power management systems, load switches, DC-DC converters, and battery management systems.
