N-Channel 30 V 5.7A (Ta) 1.4W (Ta) Surface Mount SOT-23-3 The AO3400A N-Channel MOSFET is a 30V N-channel enhancement-mode MOSFET designed using trench MOSFET technology. It is widely used for load switching, DC-DC converters, motor driving, and PWM control applications due to its very low on-resistance and compact SOT-23 package. It is especially popular in small electronics and embedded systems because it can be driven directly by 3.3V or 5V logic signals, making it ideal for microcontroller-based designs. Key Features Drain-Source Voltage (VDS): 30V Continuous Drain Current (ID): up to 5.7A (at 25°C) Ultra-low RDS(on): ~26.5 mΩ @ VGS = 10V ~32 mΩ @ VGS = 4.5V ~48 mΩ @ VGS = 2.5V Logic-level gate drive (works well with MCU GPIOs) Fast switching performance (ns-range switching times) Low gate charge (~6–7 nC) → efficient switching Compact SOT-23 package for space-saving PCB design Low power dissipation (~1.4W typical at 25°C ambient) Operating temperature: −55°C to +150°C Typical Applications Load switching (LEDs, sensors, small motors) Power management in battery-powered devices DC-DC converters PWM control circuits Fan and heater control in embedded systems #AO3400A #MOSFET #NChannelMOSFET #PowerElectronics #SOT23 #LoadSwitch #EmbeddedSystems #ElectronicsComponents #TrenchMOSFET #Commonpartslibrary #Transistor #FET
