STF6NK50Z-VB Product Introduction
STF6NK50Z-VB is a **unipolar N-type power MOSFET** in a **TO220F** package suitable for **medium voltage and current applications**. Based on **Plannar technology**, this MOSFET has a **650V** drain-source voltage (VDS) and a **7A** maximum drain current (ID). Its **Vth** (turn-on voltage) is **3.5V**, enabling it to operate stably under common gate drive voltages. Although **RDS(ON)** is **1100mΩ** at **VGS=10V**, the higher on-resistance makes it more suitable for medium-power applications where efficiency requirements are not extreme, especially in **high voltage power systems** and **low current loads**.
