Product Introduction
SM2A18NSV-VB is a single N-channel MOSFET in a SOT223 package, designed for low-power, high-voltage applications. With a maximum drain-source voltage (V_DS) of 200V and a maximum drain current (I_D) of 1A, this model is suitable for switching and control functions in medium voltage environments. Its gate-source voltage (V_GS) is ±20V, turn-on voltage (V_th) is 3V, and on-resistance (R_DS(ON)) is 1200mΩ (V_GS = 10V), which is suitable for low-current, low-power applications. This MOSFET uses Trench technology and has excellent switching performance and thermal management characteristics, which can effectively reduce switching losses. SM2A18NSV-VB is commonly used in battery-powered devices, low-power power modules, and occasions requiring high voltage and low current control.
