STD9NM50N-VB Product details
Back to previous pageProduct introduction：
1. **Product Introduction:**
The STD9NM50N-VB is a unipolar N-type MOSFET in a TO252 package with a drain-source voltage (VDS) of 650V, suitable for applications in high voltage environments. The maximum drain current (ID) of this MOSFET is 9A, which is suitable for medium-power power systems. Its on-resistance (RDS(ON)) is 500mΩ at VGS=10V. Although relatively high, its high withstand voltage characteristics enable it to still have good performance in scenarios requiring high voltage operation. The device uses SJ_Multi-EPI technology, which helps to improve current carrying capacity and power efficiency, and performs well in power control and conversion, making it suitable for efficient power systems and power converters.
