STF5NK52ZD-VB Product Introduction
STF5NK52ZD-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), which enables it to have good performance in power management and switching applications. Its **Vth** (turn-on voltage) is **3.5V**, ensuring reliable operation under typical gate drive voltages. Although **RDS(ON)** is **1100mΩ** at **VGS=10V**, the higher on-resistance limits its high-efficiency application, but it is still suitable for medium and low power systems where efficiency requirements are not extreme, especially in situations with higher voltage requirements.
