9A, 500V N-CHANNELPOWER MOSFET The UTC 9N50 is an N-channel mode power MOSFET usingUTC’s advanced technology to provide customers planar stripe andDMOS technology. This technology allows a minimum on-stateresistance, superior switching performance. It also can withstandhigh energy pulse in the avalanche and commutation mode.The UTC 9N50 is generally applied in high efficiency switch modepower supplies, active power factor correction and electronic lampballasts based on half bridge topology.
