SAMWIN Features N-Channel MOSFET BVDSS (Minimum) RDS(ON) (Maximum) ID Qg (Typical) PD (@TC=25 ) : 60 V : 0.023ohm : 50 A : 30 nc : 130 W SW50N06 General Description This power MOSFET is produced in CHMC with advanced VDMOS process, planar stripe. This technology enable power MOSFET to have better characteristics, such as fast switching time, low on resistance, low gate charge and especially excellent avalanche characteristics. It is mainly suitable for half bridge or full bridge resonant topology like a electronic ballast, and also low power switching mode power appliances.
