Product Introduction: SF3031L-VB
SF3031L-VB is a high-performance N-channel MOSFET in SOT223 package, designed for medium voltage applications. The maximum drain-to-source voltage (V_DS) of this MOSFET is 60V, and the gate-to-source voltage (V_GS) is ±20V, which is suitable for power electronic equipment that requires medium voltage and high current. Its threshold voltage (V_th) is 1.7V, which can be effectively turned on at a low gate voltage. SF3031L-VB has a low on-resistance (R_DS(on)), which is 85mΩ (V_GS=4.5V) and 76mΩ (V_GS=10V), respectively, ensuring excellent efficiency and low power loss, and the maximum drain current is 4.5A. Using Trench technology, it provides fast switching characteristics and low conduction losses, and is suitable for various electronic products that require high performance and stability.
