Working Principle of FQPF16N25

FQPF16N25 is an N-Channel enhancement mode MOSFET. It works by varying the amount of electrical current passes through the channel between the source and the drain using a gate voltage. This gate voltage can be controlled in order to control the flow of current. Greater gate voltage will increase the current flow, while lower gate voltage will reduce it.

The on-state resistance of FQPF16N25, also known as R_DS(ON), is a measurement of the resistance of the circuit when the transistor is switch on. The lower the resistance, the greater the current flow. The input capacitance of FQPF16N25, also known as C_iss, is a measurement of the amount of charge stored in the gate-drain capacitive junction in the device when a regular small change in input voltage is applied. Higher value of C_iss will result in greater storing capacity of charge in the gate-drain junction.

In addition, FQPF16N25 has a low junction capacitance, which is a measure of the capacitance between the drain, source and gate of the device. The lower the junction capacitance, the higher the switching speed. The maximum drain-source voltage (V_DS) of FQPF16N25 is 100V, with a maximum operating temperature of 175°C.

In conclusion, FQPF16N25 is a high-frequency N-channel MOSFET with high performance, low on-state resistance and high input capacitance. It is suitable for use in a variety applications including RF amplifiers, low-noise amplifiers, digital-to-analog converters, television equipment, and microwave units.
