Working Principle

The BUK6218-40C,118 uses a 3-terminal MOSFET, which has a source, a drain and a gate. When a voltage is applied to the gate terminal of the MOSFET, electrons in the channel are either filled or depleted depending on the type of device. In the case of an N-channel MOSFET, applied voltage to the gate causes an excess of electrons to drift in and out of the channel, creating an accumulation of negative charge in the channel. This in turn increases the channel’s resistance and lowers the flow of current through the MOSFET.

The size of the gate voltage required to achieve a certain level of drain current is also directly proportional to the threshold voltage or V_TH. This is the voltage that is required to turn on the device fully. Additionally, this voltage determines the on-state resistance of the MOSFET. This product has a low V_TH and low on-state resistance which makes it an ideal choice for switching applications.
