Product introduction：
1. Product Introduction
**SM2300NSAC-VB** is a high-performance unipolar N-Channel MOSFET in a small SOT23-3 package, designed for low voltage and high efficiency applications. The maximum drain-source voltage (VDS) of this MOSFET is 20V, which is suitable for electronic circuits that require low voltage operation. Its threshold voltage (Vth) is between 0.5V and 1.5V, and it can start to conduct at a lower gate voltage, which is very suitable for low power systems. This model has a low on-resistance (RDS(ON)), which is 42mΩ (at VGS=2.5V) and 28mΩ (at VGS=4.5V) at different gate drive voltages, which can provide higher efficiency at low currents and high switching frequencies. The maximum drain current (ID) is 6A, which is suitable for low and medium power current control and switching applications.
