WFF840-VB Product details
Back to previous pageProduct introduction：
**
WFF840-VB is a single N-channel MOSFET in TO220F package, designed for medium to high power and high voltage applications. It has a drain-source voltage (VDS) of 650V and a maximum drain current (ID) of 12A. The on-resistance (RDS(ON)) of this MOSFET is 680mΩ (@VGS=10V). Although its on-resistance is higher than other low on-resistance MOSFETs, it can still provide stable operating performance. WFF840-VB uses Plannar technology, which has good voltage tolerance and stability, and is suitable for various power electronic devices that require higher voltage tolerance. The design of this MOSFET makes it very suitable for use in power management, switching power supplies and medium-power industrial circuits.
