SM4331PSK-VB MOSFET Product Introduction
SM4331PSK-VB is a high-performance P-channel MOSFET in SOP8 package, designed for medium and low voltage high current switching and power management applications. It uses Trench technology and has ultra-low on-resistance (RDS(ON)), which can significantly reduce power loss and improve system energy efficiency. The maximum drain-source voltage (VDS) of this MOSFET is -30V and the gate-source voltage (VGS) is ±20V, which is suitable for high-efficiency power control and switching applications under high current loads.
The threshold voltage (Vth) of SM4331PSK-VB is -3V, which can work effectively at a lower gate voltage. Its on-resistance is 8mΩ at VGS = 4.5V, which is reduced to 5mΩ at VGS = 10V, providing excellent current switching capability and supporting a maximum drain current (ID) of -18A. This MOSFET is suitable for various fields such as high-efficiency power management, load switching, inverter and battery management.
SM4331PSK-VB has excellent thermal management characteristics and long-term stable working performance. It is an ideal choice for high-efficiency power design in many fields such as industry, automobile, consumer electronics and communication equipment.
