Product introduction：
Product Introduction
**STP3NA90-VB** is a **unipolar N-type MOSFET** in **TO220** package with **900V** high voltage withstand capability, suitable for applications requiring high voltage isolation. This MOSFET uses **SJ_Multi-EPI technology** and has good electrical characteristics and reliability, especially in the high voltage and high power fields. Its **VGS** is **±30V**, the maximum drain current **ID** is **5A**, and it has a **high on-resistance** (**RDS(ON) = 1500mΩ**). Although the on-resistance of this device is relatively high, it is still suitable for some high voltage but low current applications, such as power switches, drive circuits and some power conversion applications.
