STW9NK90Z-VB Product Introduction
**STW9NK90Z-VB** is a high-voltage single N-channel power MOSFET in a TO247 package, designed for applications that require higher voltage tolerance. This model has a drain-source voltage (VDS) of 900V and can support a drain current (ID) of up to 9A. By adopting advanced SJ_Multi-EPI technology, the STW9NK90Z-VB provides a low on-resistance (RDS(ON) of 750mΩ@VGS = 10V), which helps to improve power conversion efficiency and reduce thermal losses. Vth is set to 3.5V, making it very stable and reliable under normal operating conditions. This model is particularly suitable for high-frequency, high-power and switching applications that require high voltage and high reliability.
