Product introduction：
Product Introduction:
**STP32NM50N-VB** is a high-voltage **N-Channel MOSFET**, which adopts **TO220** package and is designed for high-voltage and high-current power electronics applications. This model has a high drain-source voltage (VDS) of 500V, which is suitable for high-voltage switching applications. Its maximum gate-source voltage (VGS) is ±30V, ensuring stable operation under various control signals. The gate-source threshold voltage (Vth) is 3.5V, which is suitable for driving medium-voltage control signals. The on-resistance (RDS(ON)) of this MOSFET is 140mΩ at VGS=10V, which is suitable for high-voltage power supply systems that require medium on-resistance and can balance power loss and efficiency. The maximum drain current (ID) is 30A, which is suitable for applications requiring larger current loads. This model adopts **SJ_Multi-EPI technology**, which further improves its high-voltage performance and switching characteristics.
