Product Introduction
**STP5NB90-VB** is an **N-type power MOSFET**, packaged in **TO220**, with a **900V** high drain-source voltage (VDS) and **30V** gate-source voltage (VGS). This product uses **SJ_Multi-EPI** technology to provide high-efficiency power switching functions. The **Vth** (threshold voltage) of the MOSFET is **3.5V**, making it suitable for efficient switching in high-voltage environments. Its **RDS(ON)** is **1500mΩ** at **VGS=10V**, which is slightly higher than some low-on-resistance MOSFETs, but still provides good performance for applications requiring higher voltages. This MOSFET is capable of providing a maximum drain current (ID) of **5A**, suitable for medium-to-high voltage, medium-current power control applications. Its high **VDS** and stable performance make it widely used in **switching power supplies, power amplifiers, battery management systems** and other fields.
