Working Principle of FDPF4D5N10C
The FDPF4D5N10C is an enhancement mode N-channel power field effect transistor (FET) specifically designed for high frequency switching applications. It is constructed with a monolithic double poly silicon gate CMOS process using advanced technologies. The current is controlled and limited to a safe range through the drain-source pinch off region.

The FDPF4D5N10C has an internal enhancement mode gate structure and requires no gate voltage to be applied in order to turn on. An injected gate voltage greater than its threshold gate voltage will cause a channel between the gate and drain. A small amount of current will then flow through the source-drain path, with the magnitude of the current proportional to the gate voltage.

The FDPF4D5N10C has an integrated protection diode from gate to source, which prevents an excessive voltage from being applied. It also has an antistatic device for each field effect transistor to prevent damage to the gate, drain, or source.

The FDPF4D5N10C is reliable, efficient and easy to use since it has an internal gate protection to minimize gate stress and ultra-low gate charge for a more efficient switching. It also has a wide range of operating temperatures and is available in both surface mount and through-hole form.
