Bipolar Junction Transistors (BJTs) are sometimes referred to as "3-terminal" transistors because of their three terminals, collector, base and emitter. They are used for functions such as switching, amplifying and to control current flow. A single TIP102TSTU transistor is a popular choice for electronic engineers when looking for an NPN transistor able to pass up to 15A and handle up to 80V.

Component Description

The TIP102TSTU is an NPN silicon power transistor in an epoxy package which helps with protection against heat and moisture. Its three contacts pass current from the collector to the emitter with the base serving as a controlling element. The introduction of an electrical current at the base terminal allows for current to be passed from the collector to the emitter. The TIP102TSTU is suitable for applications such as drivers, relays, switching regulators, switching power supply and voltage regulators.

Pinout Diagram

The TIP102TSTU has the following pinouts:

• Pin 1 (Collector) - The collector is the port into which the current flow enters the transistor.
• Pin 2 (Base) - The base controls the current flow from collector to emitter.
• Pin 3 (Emitter) - The emitter is the port from which the current leaves the transistor.

Typical Characteristics

The TIP102TSTU\'s typical characteristics include:

• Collector-base breakdown voltage (BV(CBO)} - 80V
• Collector-emitter breakdown voltage (BV(CEO)) - 60V
• Emitter-base breakdown voltage (BV(EBO)) - 5V
• Collector current rating (IC) - 15A
• Drain-source breakdown voltage (Pulse) - 91V
• Gain Bandwidth (Ft) - 1MHz
• Collector-emitter saturation voltage (VCE(sat)) - 1.5V
• Gain (hFE) - 40 - 140

Working Principle and Application Field

The TIP102TSTU is made from two p-n junction diodes, forming an NPN transistor device. When the gate voltage is positive enough the transistor will switch on, allowing current to flow between the collector and emitter. The transistor acts like a switch, and is often used to amplify current, or to control current flow.

The TIP102TSTU is predominantly used for medium-power applications. It can obtain up to 15A, and when used in conjunction with a heat sink can obtain higher current capabilities. It is used in switching applications (such as motor control), amplifying applications and for current regulation. It is also commonly used in electrical engineering and robotics projects.

Conclusion

In summary, the TIP102TSTU is a popular choice for medium-power applications, due to its robustness and current handling capabilities. It is able to switch on and off relatively quickly, and its current amplification and current regulation capabilities make it a suitable choice for many projects. Understanding the pinout and operation of transistors is a crucial part of understanding electrical engineering and robotics, and the TIP102TSTU is a great choice to learn with.
