Switches
A switch is a device that allows electricity to flow through a circuit by completing or interrupting the connection. It is a common component in electrical and electronic systems and is used in a variety of applications, such as controlling the flow of electricity in a circuit, turning devices on and off, and routing electrical signals. One of the primary use cases for switches is to control the flow of electricity in a circuit. This can be done by manually flipping the switch or by using a control mechanism, such as a timer or a sensor. Another common use for switches is to turn devices on and off. This can be done using a switch that is built into the device or by using a separate switch that is connected to the device. In addition to these basic use cases, switches can also be used to route electrical signals. For example, a switch can be used to route a signal from one device to another or to direct a signal to a specific circuit or component. If you're looking for a wide variety of switches for your projects, flux.ai has the world's largest community-driven public library of them. The library includes footprints, symbols, datasheets, and simulation models for a wide range of switches, making it easy to find the right switch for your needs.
AO3400A
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
