Transistors are commonly used to amplify electrical signals. TPC8026 (TE12L, Q, M) is a type of specialty field-effect transistor (FET), which belongs to single MOSFET operated by one gate. The device has especially gained popularity over the past few years due to its low-voltage, low-power features and wide variety of applications.

This amazingly versatile transistor has both its benefits and possible disadvantages due to its extremely small size and ultimately its limited capabilities. Despite its limited capabilities, the TPC8026 has a few key uses as follows.

Motor Control Applications

By using the TPC8026, motor control circuit applications that require low voltages, low currents, and minimal power can easily be achieved. It works by implementing the MOSFET gate to act as a switch. When the high voltage input is on, the gate is kept open, allowing for the current to flow to the motors. In contrast, when no voltage is detected, the MOSFET gate closes, ceasing the current flow. Since the TPC8026 operates on such small power devices, these kinds of applications do not require an excessive amount of energy.

Audio Amplifier Applications

The TPC8026 is also commonly used in audio amplifier applications. It works by allowing the FET in the TPC8026 to detect small electrical signals varying in voltage and current. These signals act as individual notes and can require amplification so they can be heard by the listener. Fortunately, the TPC8026’s low-voltage, low-power characteristics make it ideal for such applications.

Measurement Applications

Due to the TPC8026’s small size and low power requirements, it is also widely used in measurement applications. This is because it is able to respond quicker to changes in voltage and current. For example, if a current passes through the transistor, it can be used to measure the magnitude of the current, thus providing information about the device or equipment that the current is passing through.

Working Principle

The TPC8026 is a single MOSFET operated by one gate, which works by controlling the flow of current from the source to the drain terminal. It is important to understand that a MOSFET consists of four components: source, drain, gate, and body. The source is where current enters the transistor, while the drain denotes the exit path of the current. The body is the silicon substrate base of the transistor, while the gate provides the switching control of the current. When the gate receives a low voltage, the path of current between the source and the drain is open. On the other hand, when the gate is receiving a high voltage, the current is out blocked. Therefore, it is the voltage applied to the gate that switches the current on/off.

Conclusion

The TPC8026 is an extremely useful transistor due to its simplicity and its multiple applications. Its low-voltage and low-power features allow it to perform various functions, such as motor control, audio amplification, and measurement. Its working principle revolves around the FET gate that is used to switch the current on or off depending on the applied voltage. The TPC8026 is an excellent choice for applications that require low voltages and low current circuits.
