2SA1759T100P Application Field and Working Principle

The 2SA1759T100P is a silicon PNP transistor of the single bipolar junction type (BJT) from a family of high-speed switching transistors. This type of BJT has two p-type and one n-type silicon semiconductor layers, hence the term "bipolar." It is designed for medium-power electronic switching applications.

Application Fields

The 2SA1759T100P is used for high-speed switching applications such as high-speed switching relays and power converters. It is also used in motor control, domestic appliances, industrial control and consumer products, automotive applications and similar applications that require a switching action.

Working Principle

The 2SA1759T100P BJT operates using a basic principle of conducting current through a base and emitter region to produce an amplified current in the collector. The base terminal serves as the pathway for a current flow, and the emitter terminal is the pathway for a return current, creating a circuit. The current gain of the transistor is determined by the ratio of the collector current to the base current, commonly referred to as hFE. The 2SA1759T100P has hFE values ranging between 100 and 150.

When the base terminal of the transistor is connected to the positive side of the power supply, current flows through the base into the collector, and the transistor turns "on." When the the base is connected to the negative side of the power supply, the transistor is turned "off." The collector current of the transistor, which flows from the collector to the emitter, is amplification of the current supplied to the base, and can range from a fraction of an ampere to several hundred amperes, depending on the type of transistor.

The 2SA1759T100P is designed for high-speed switching applications. It can be used in switching relays and voltage- and frequency-controlled power converters, allowing rapid switching of high power circuits. This type of transistor is often used in automotive, consumer, and industrial applications to switch high power DC signals.
