Applications

CSD18504KCS is used in a wide variety of switching applications. It can be used in low voltage DC-DC converters for load current up to 8A. It is also suitable for load switching, Inrush current limitation and load current sensing. This MOSFET is suitable for powering automotive applications and industrial applications such as PC motherboards, cellular phones, and home appliances.

Working Principle

The CSD18504KCS works on the principle of a MOSFET. A MOSFET is a field effect transistor (FET) that operates by controlling the flow of electrons through a gate region. The gate region is formed between a pair of P-N junctions, referred to as the source, drain, and gate terminals. The source and drain are connected to a power source and to the external circuit, respectively. When a voltage is applied to the gate terminal, the resistance between the source and drain terminals changes depending on the voltage applied.

When no voltage is applied to the gate terminal, the MOSFET is said to be “off”, meaning that no current is allowed to flow from the source to the drain. When a voltage is applied to the gate terminal, the resistance between the source and the drain terminals decreases, allowing current to flow through the device. This is referred to as the “on” state, and the current flowing through the device is proportional to the voltage applied to the gate terminal.

The CSD18504KCS is a N-Channel MOSFET, meaning that the current flows from the source terminal to the drain terminal (in the “on” state) when the gate voltage is increased. The device has a very low resistance in the “on” state, resulting in extremely low power dissipation and improved thermal performance.
