A FQPF2N90 is a voltage driven field effect transistor (FET) composed of a single Polycrystalline-Silicon (Poly-Si) layer, which serves as the gate, contacted by source and drain electrodes. The FQPF2N90 has become increasingly popular due to its low on-resistance and low threshold voltages. This type of transistor is commonly used to handle pulse suppressing, biasing circuits, power conversion and motor control, as well as other applications.

Operation Principle:

FQPF2N90 semiconductor transistors are based on metal–oxide–semiconductor field–effect transistor (MOSFET) technology, which allows the flow of electric current between the source and the drain when the voltage at the gate electrode is greater than the threshold voltage. The FQPF2N90 uses a single Poly-Si layer, which serves as the gate, to control the flow of current between the source and the drain. When voltage is applied at the gate electrode, the electron tunneling movement of electrons between the source and the drain takes place, allowing current flow. This type of FET is characterized by low on-resistance and low threshold voltages.

Features:

• Low on-resistance: The low on-resistance and low threshold voltages of the FQPF2N90 reduce power loss and provide improved reliability.
