AO7400L application field and working principle
AO7400L is a kind of low-voltage, high-speed N-channel MOSFET (Metal–oxide–semiconductor Field Effect Transistor). It is widely used in various kinds of drive, amplifying and switching application fields.
Fields of Application
AO7400L is mainly used in applications such as PC peripheral, LED driver, power conversion, and high-precision power amplifier. The AO7400L can carry current up to 3A and can operate up to -55°C to +150°C. Its powerful on-state resistance (RDS) and wide bandwidth coupled with fast switching speed make it perfect for use in a variety of power applications.
Working Principle
MOSFETs are special type of transistors which are used to control power in all kinds of electronic devices. A MOSFET consists of a three-terminal structure – gate, source and drain. When a voltage is applied to the gate, it modulates the current that passes through the channel between the source and drain. This causes the channel to become either completely off or completely on depending on the voltage.
The AO7400L MOSFET is an enhancement-type MOSFET, meaning that when the gate voltage is low, the transistor is in the OFF state and the output is zero. Increasing the gate voltage to a positive level turns the transistor ON and allows current flow between the source and drain.
The AO7400L is designed for low-voltage (3.3 V and under), high-current applications. Its below-mentioned features make it suitable for applications that require high speed, low power dissipation and low noise generation.
Features: 
Low-voltage operation.
High-speed switching.
Low noise generation.
Compact package.
