The 2N7224 is a N-Channel Junction Field-Effect Transistor (JFET) manufactured by Motorola. This device is part of the second generation of JFETs and it is used for voltage or current amplification when a medium-to-high impedance source is needed. This JFET also provides noise immunity and low power consumption, making it an ideal choice for many applications. It can be used in power amplifiers, voltage mirrors, impedance matched amplifiers, and many other circuits. In this article we will discuss the application field and working principle of the 2N7224.

Application Field of the 2N7224

The 2N7224 is a N-Channel JFET and it is used in many different fields. It can be used in amplifiers, voltage controlled resistors, voltage regulators, voltage followers, frequency multipliers, active filters, and more. It is also commonly used as a buffer, as it allows signals to bypass amplification stages while maintaining low distortion levels. Furthermore, it is commonly used in audio applications due to its ability to provide an extremely clean signal path, while still providing good control of current transfer. It is also applicable to medical and military applications, where resistance to vibration and wide temperature range is important.

Working Principle of the 2N7224

The 2N7224 is a N-Channel JFET and it works by transferring electric current through a semiconductor material when its Gate voltage is applied. The semiconductor material consists of two parts, the N-type region which is where the current flows, and the P-type region which acts as the body or channel. When a positive voltage is applied to the Gate terminal, it creates a strong electric field between the N-type and P-type region, resulting in the flow of current. This flow of current is known as the Drain current or Drain-Source current. The current flow is proportional to the Gate voltage and is normally limited by the two P-N junctions located in the semiconductor material.

The Drain-Source voltage is also an important aspect to consider when using the 2N7224. The Drain-Source voltage is the voltage between the Drain and Source terminals of the JFET and it affects the Drain current. When the Drain-Source voltage is increased, the Drain current decreases. This feature is commonly used to control the output current. It is also important to note that the Gate terminal should be biased in order to maintain a low input impedance and a low gate-drain capacitance.

Conclusion

The 2N7224 is a N-Channel Junction Field-Effect Transistor that can be used for a variety of applications. It is commonly used for voltage or current amplification and it provides noise immunity, low power consumption, and low distortion levels. Additionally, it is also applicable to medical and military applications, due to its resistance to vibration and wide temperature range. The working principle of the 2N7224 is based on the transfer of electric current through a semiconductor material when its Gate voltage is applied.
