Product introduction：
1. Product Introduction: SSP4N70-VB is a single N-channel MOSFET in a TO220 package, designed for high voltage and medium power applications. The drain-source voltage (V_DS) of this MOSFET is as high as 700V, which can work stably under high voltage environment and is suitable for high power circuits. Its maximum drain current (I_D) is 4A, which has strong current carrying capacity and can meet the requirements of industrial applications. The gate-source voltage (V_GS) range is ±30V, and the threshold voltage (V_th) is 3.5V, which can adapt to a variety of switch control conditions. The on-resistance (R_DS(ON)) is 2600mΩ at V_GS=10V. Although the on-resistance is high, this MOSFET can still effectively perform high voltage switch control, especially for occasions that require high voltage resistance.
SSP4N70-VB adopts **Plannar technology**, which is characterized by its relatively mature manufacturing process, good temperature stability and durability, and is suitable for high current and high voltage application environments.
