Working Principle

The working principle of IRFP4568PBF is based on power MOSFET fabrication technology. Basically, a power MOSFET consists of a source, a bulk, a gate and a drain. The power MOSFET structure, including the semiconductor material and etched areas, is a combination of a n-channel enhancement-mode power transistor and a silicon-oxide passivation layer. The power MOSFET body protects the semiconductor material and reduces the gate-body capacitance, which extends the transconductance and switching time of the power MOSFET. The gate is used to activate the power MOSFET and the drain is used to collect the current. The source is used to protect the gate and to provide a connection to the gate voltage. The gate voltage can be changed as per the required switching needs.
