Product Introduction
**STF7N52DK3-VB** is a 650V single N-channel MOSFET in a TO220F package suitable for medium and high voltage power management and power control applications. This MOSFET uses Plannar technology and has good current carrying capacity (maximum drain current 7A) and high reliability design suitable for medium voltage (VDS=650V) systems. Although its on-resistance (RDS(ON)=1100mΩ@VGS=10V) is high, it is suitable for applications that do not require extremely low losses, especially in power systems that are cost-sensitive and do not require extreme efficiency, it can still provide stable performance.
This model of MOSFET is widely used in power management, power tools, inverters and automotive electronic systems, especially in applications with high voltage requirements but not particularly large current requirements.
