The FDD86540 by Fairchild Semiconductor is a N-channel logic level FET (Field-Effect Transistor). It is part of the FDD8654x series of P-channel FETs developed by Fairchild.

The FDD86540 is designed for applications that require high speed switching, low on-resistance, and low power drain. It is suitable for use in high current, high-side switching applications, and is able to handle currents up to 12 A.

The device is housed in a with a TO-326 package and has an active area of 7 mm2. It is available in three different versions: standard, low RDSon, and high RDSon.

The FDD86540 works by using a transistor to control the electric current flowing through a circuit. It applies a positive voltage to the gate of the FET, which causes the FET\'s channel to open, allowing electric current to flow through it. The electric current is then regulated by applying a negative voltage to the gate, which causes the FET\'s channel to close, stopping the electric current from flowing through it. The electric current will remain off until the positive voltage is applied again.

The FDD86540 is commonly used in high-power switching applications such as motor control and power management. It can also be used in automotive and other power electronics applications. Additionally, the FDD86540 is well suited for use in 3-phase motor control and other automotive systems, as it is designed to provide a low on-resistance, high switching speed and high current carrying capability.

The FDD86540 also has a high breakdown voltage, allowing it to handle large voltages and currents. The device also has a high electrostatic discharge (ESD) rating, which makes it suitable for use in systems that encounter high voltages, such as the automobile industry. The device is also resistant to temperature changes, making it ideal for use in a wide range of applications.

The FDD86540 can be used as a high-side switch, allowing for precise control of the current and voltage in a circuit. The device is also well suited for use as a power switch in automotive audio and multimedia systems, as it can handle high voltages and currents. Additionally, the FDD86540 can be used to regulate the current and the voltage in a power system, making it an ideal choice for applications requiring precise voltage and current control.

In conclusion, the FDD86540 is an excellent device for a wide range of high-power switching applications. It has a low on-resistance, high switching speed, and high current carrying capability, making it a great choice for motor control, power management, and automotive audio systems. Additionally, the device is resistant to temperature changes and has a high ESD rating, making it suitable for use in a wide range of applications. Therefore, the FDD86540 is an excellent device for a variety of applications.
