FQI15P12TU Working Principle
To understand how FQI15P12TU works, it is important to understand the structure and function of the transistor. The MOSFET is a four layers of alternating P-type and N-type semiconductor materials, which control a volume or current flow between two terminals. The terminals are known as the source, the drain, and the gate.
The FQI15P12TU has a P-type source and N-type drain. Applying positive voltage from the gate to the source will cause more electrons to flow from the drain to the source. This constitutes an "enhancement mode" MOSFET, as it increases with increasing gate voltage. This is the primary conduction mechanism of FQI15P12TU.
When the gate voltage is decreased, the current flowing from the drain to the source will reduce accordingly. When the gate voltage is negative, the current from the drain to the source is cut off, and the device is said to be "pinch off". This is known as the "depletion mode" and is the second conduction mechanism of FQI15P12TU.
In summary, FQI15P12TU transistors can be used in a variety of applications and comes with two conductive mechanisms that can be used to control electric flow: the enhancement mode and depletion mode.
