Back to previous pageProduct introduction：
1. Product Introduction (STP9NK90ZFP-VB)
STP9NK90ZFP-VB is a high-performance unipolar N-channel MOSFET in TO220F package, designed for high voltage and high power applications. It has a maximum drain-source voltage (Vds) of 900V and can operate stably in high voltage environments. The gate-source voltage (Vgs) of this MOSFET is up to ±30V, suitable for power conversion and switching applications that require high voltage tolerance and high efficiency.
STP9NK90ZFP-VB provides a low on-resistance (Rds(on)@Vgs=10V) of 770mΩ, which can effectively reduce switching losses and improve the energy efficiency of the system. Its maximum drain current (Id) is 7A, making it suitable for medium and high power loads. Using SJ_Multi-EPI technology, it provides lower on-resistance, faster switching response and higher reliability, making it widely used in inverters, power management and motor drives.
