Product Introduction: SM1A23NSD-VB MOSFET
SM1A23NSD-VB is a unipolar N-channel MOSFET in a SOT-89 package, designed for high-efficiency switching applications. Its maximum drain-source voltage (VDS) is 100V, which is suitable for power supplies and switching circuits in the medium power range. It has a low on-resistance (RDS(ON) of 125mΩ @VGS=4.5V, 102mΩ @VGS=10V), ensuring efficient power transmission and reducing heat loss. The threshold voltage (Vth) of this MOSFET is 1.8V, which means that it can achieve effective switching control at a lower gate voltage. SM1A23NSD-VB uses Trench technology, has a low on-resistance and excellent switching performance, and is widely used in power management, power conversion, load switching and other fields.
