Product introduction：
**
STP3NK80Z-VB is a single N-channel MOSFET in TO220 package, designed for high voltage switching applications, using Plannar technology. With a drain-source voltage (V_DS) of up to 850V and a maximum drain current (I_D) of 4A, this MOSFET is suitable for applications requiring high voltage and high reliability. Its gate-source voltage (V_GS) can withstand a maximum of ±30V, and its threshold voltage (V_th) is 3.5V. The on-resistance (R_DS(ON)) of STP3NK80Z-VB is 2700mΩ (at V_GS = 10V), which enables it to maintain relatively low power loss in high voltage environments. The high voltage withstand characteristics and stable switching performance of this MOSFET make it suitable for power management, switching power supplies, motor drives and other power electronics applications.
