HAT2261H-EL-E is a kind of field effect transistor (FET) that belongs to a type of single, MOSFETs (metal–oxide–semiconductor field-effect transistor). Due to its wide range of applications and its particular working principle, this type of transistor has enjoyed great popularity in the electronic industry.

The HAT2261H-EL-E is composed of four terminals, namely the drain, gate, source and body. The body (corresponding to the substrate) is the connection to the semiconductor body, which acts as a connectivity and provides the connection for both the gate and the source. Of these terminals, the gate is the control terminal, allowing for current to flow within the transistor and controlling the drain-source current. The drain is the current output section of the transistor, and the source is considered the opposite and serves as the current input. The substrate and gate are usually connected to the power source, while the drain and source are connected to the circuit.

The HAT2261H-EL-E has a wide range of applications due to its versatile construction. It has commonly been used as an amplifier in various circuits, becoming an ideal component for generating audio signals. This kind of FET also is used in the logic level shifters in order to increase the output voltage to drive the gates of other FETs, as well as in power switches to control the current and voltage level of the system. Additionally, the HAT2261H-EL-E can be incorporated for power supply circuits or other gate array or direct gate drive.

The HAT2261H-EL-E processes the input signal from the gate to the drain-source region by the action of an oxide insulated gate. In this process, there is no current flow from gate to the source. Instead, it follows the drain-source current when a voltage is applied at the gate. This type of FET has no additional bias current for the operation and thus power consumption is low. Once the input is applied to the gate, an electric field becomes active that is dependent on the voltage and the threshold voltage, which serves as a transition point between off and on-state.

The main advantage of HAT2261H-EL-E lies in the lack of current flow from gate to source, providing the transistor with high input impedance, while the drain-source current is highly proportional to the input control voltage. This device is also better when compared to a BJT for its faster switching time, its low noise, and its low power consumption. This FET can operate between -55 and 175 C, however, its immunity to radio frequency interference is often compromised when exposed to temperature over 100 C.

To summarize, HAT2261H-EL-E is a kind of single, MOSFETs (metal–oxide–semiconductor field-effect transistor), mainly suitable as an amplifier, power switch, and level shifter. It features a low noise, fast switching time and low power consumption. It has a wide range of working temperature, however, its resistance to radiofrequency interference is reduced when over 100 C.
