FDB5645 is a silicon-based N-Channel Metal Oxide Semi-Conductor Field Effect Transistor (MOSFET). It is manufactured by Fairchild Semiconductor and often used in DC voltage regulators, high power switch circuits, and even in audio amplifiers.

FDB5645 is a popular field effect transistor (FET) and is a single transistor device. It is composed of two conductive gates, an insulated source and a drain. The source and drain are conductive and therefore can connect to electronic components or circuit boards. The gates are isolated from each other and connected to the source and drain using different elements. The amount of current that can be transferred through the transistor depends on the amount of voltage applied to the different elements of the transistor.

FDB5645 has a maximum forward Pulsed Drain Current of up to 10 Amps and a Pulsed Drain Voltage of up to 30 Volts. The FET also has a very low On-Resistance (RDSon) of just 0.06 Ohm. This makes the FET ideal for applications that require high-power switching and controlling high currents in a short amount of time. For example, FDB5645 is often used in DC voltage regulators, which are used to reduce the output voltage of a DC-powered device to safe levels. The low RDSon of the transistor makes it ideal for high-current and rapid switching requirements.

In addition to high-power switch circuits, FDB5645 is also popularly used in audio amplifiers. In these applications, the high RDSon of the transistor ensures minimum energy losses. This ensures a clear and undistorted sound when connected to a high-frequency input. The FDB5645 evenly distributes the current and voltage used throughout the amplifier circuit and allows the circuit to work efficiently with minimal losses.

The working principle of FDB5645 is fairly simple. The voltage applied to the Gates determines the current flowing between the Source and the Drain. This is known as the Drain-Source Voltage (VDS). When the VDS is lower than the threshold voltage (Vth), no current will flow through the FET. However, when the VDS exceeds the Vth, the FET will allow current to pass through it. This means that the FET can be used to amplify or attenuate the current passing through it. For example, with a high VDS, the output current from the FET can be amplified or increased.

In conclusion, the FDB5645 is a silicon-based N-Channel MOSFET device manufactured by Fairchild Semiconductor. It is often used in applications such as DC voltage regulators, high power switch circuits, and audio amplifiers due to its high Pulsed Drain Current, Pulsed Drain Voltage, and low On-Resistance. The working principle of FDB5645 is based on the current that flows between the Source and the Drain and is determined by the Voltage applied to the Gates. Therefore, FDB5645 can be used to amplify or attenuate current passing through it.
