The 2SB1695TL transistor is a discreet, single collector-base, bipolar NPN device intended for use in a wide range of applications. It is a small, low-power device that can be used in a variety of different circuits, such as switching and amplifying, due to its convenient size and robust design. The 2SB1695TL is typically used in high sensitivity, low current, and low noise applications due to its excellent performance characteristics. This article will discuss the 2SB1695TL application field and working principle.

2SB1695TL application field

The 2SB1695TL transistor offers a broad range of application possibilities, including audio amplifiers, switching circuits, and voltage regulators. This device is commonly used for general amplifying, switching applications, and various audio circuits. It is also used for general-purpose switching, such as for energizing relays and solenoids, as well as in low voltage LED power supply circuits. Additionally, the 2SB1695TL often serves as a voltage regulator in small devices such as digital cameras, where it can be used to monitor and maintain the proper voltage.

This transistor is also well-suited for use in current-limiting circuits. By connecting the emitter-base junction of the 2SB1695TL to the Collector-Base junction of another device, a current-limiting circuit can be made. This type of circuit can prove useful in a range of applications, such as safety circuits, device protection circuits, and integrated circuits.

2SB1695TL working principle

The working principle of the 2SB1695TL is based on biasing. The transistor is composed of three terminals, called the emitter, base and collector. The bias, or applied voltage, between the base and emitter determines how the transistor will operate. In the forward-biased mode, a positive voltage is applied to the base relative to the emitter, allowing electrons to move from the emitter to the base, allowing current to flow through the transistor. In the reverse-biased mode, a negative voltage is applied to the base relative to the emitter, allowing the transistor to block current from entering the collector.

The 2SB1695TL is NPN, meaning that it is composed of two doped layers of semiconductor material, one doped with P-type material (the emitter) and one doped with N-type material (the collector). The third terminal, the base, is sandwiched between the two layers, and when a current is applied to the base, it creates a joint circuit between the emitter and collector, allowing electrons to flow between the two.

The 2SB1695TL is encapsulated with a glass–epoxy body, providing great mechanical stability and electrical insulation. This also helps to protect the transistor against shock and vibration, as well as making it easier to mount on a circuit board.
