The device has a typical RDS (on) value of 0.087Ω @ 4.5V, making it suitable for power management, LED lighting and automotive applications.

The working principle of CSD18511KTTT power MOSFET is similar to that of an ordinary FET but it uses a metal-oxide layer, also known as the ‘gate\', which acts as an insulator between the source and drain. When the voltage applied between the gate and source terminals is greater than a certain threshold voltage, carriers can pass through the oxide layer and it is said to have "turned on". The current then passes between the source and drain, while the gate-source voltage controls the magnitude of this current, making this transistor a voltage-controlled device.
