ZTX688BSTOB is a single, discrete NPN bipolar transistor. It belongs to the family of transistors known as Bipolar Junction Transistors (BJT). The ZTX688BSTOB was introduced by Zetex Semiconductors in the early 1990s and is still in use today. This article will discuss the application areas and working principle of the ZTX688BSTOB.

A bipolar transistor is a type of transistor wherein current flows between two types of doped semiconductor - the collector and the emitter. The collector and the emitter are then connected to the base which is made of a third type of doped semiconductor material. The three terminals (base, collector and emitter) of the bipolar transistor, ZTX688BSTOB, act as a switch and can either amplify or attenuate the input signal.

The ZTX688BSTOB is a general purpose transistor, making it suitable for many different applications. It is used in audio amplifiers, power supplies, voltage regulators and motor control. The ZTX688BSTOB also finds application in disc recording and playback equipments. It is also used in low frequency amplifiers, instrumentation amplifiers and communication circuits.

The ZTX688BSTOB works by using the input signal to control the current flow between the collector and the emitter. When the base is on, current flows from the collector to the emitter which then amplifies the input signal. When the base is switched off, no current passes through the base, attenuating the input signal. The gain of the transistor (or amplification factor) depends on the input current and the collector current, and can be adjusted using the principle of negative feedback.

In terms of technical specifications, the ZTX688BSTOB has an operating temperature range of -50°C to 400°C, a maximum voltage rating of 60V, a collector-emitter voltage rating of 30V and a power dissipation of 600mW. It has an hFE gain of 200 and a collector-emitter saturation voltage of 0.5V. Additionally, the ZTX688BSTOB has a junction capacitance of 3pF, making it suitable for high-frequency applications.

The ZTX688BSTOB is a reliable and versatile silicon Bipolar Junction Transistor that offers excellent performance in a wide range of applications. It is easy to use and has a wide range of technical specifications making it an ideal choice for audio amplifiers, power supplies, voltage regulators, communication circuits and motor control. The ZTX688BSTOB can be used with negative feedback to adjust the gain of the transistor. Finally, its low junction capacitance makes it suitable for high-frequency applications.
