Product Introduction
SM3337PSQG-VB is a high-performance P-channel MOSFET in DFN8 (3x3) package, designed for low-voltage and high-power density applications. Its maximum drain-source voltage (V_DS) is -30V, and the maximum drain current (I_D) can reach -45A. The gate-source voltage (V_GS) of this MOSFET is ±20V, the turn-on voltage (V_th) is -2.5V, and the on-resistance (R_DS(ON)) is 11mΩ at V_GS = 10V and 18mΩ at V_GS = 4.5V. SM3337PSQG-VB uses Trench technology, has very low on-resistance and excellent switching performance, and is suitable for high-performance, high-current applications such as power management, load switching, and motor drive.
