KSB772YSTU is a single bipolar (BJT) transistor type device manufactured by STMicroelectronics. It is a general purpose NPN transistor that can be used for a wide range of applications.

It is ideal for switching and amplifying signals for use in industrial, automotive and consumer applications. The KSB772YSTU is a low power device with a maximum collector-emitter voltage of 80V and a maximum collector current of 1.0A. The safe operating area is limited to 85degC.

KSB772YSTU is offered in an ultra-small SOT-23-5 plastic package and its features include a high-speed switching and high electrical gain. The transistor is suitable for low-level, high-speed switching in audio circuits, power switching and in many other general purpose circuits.

In operation, the NPN transistor KSB772YSTU is used to convert a small current from the base (control) terminal of the device to a larger current from the collector (output) terminal of the device. This is achieved by the transistor “amplifying” current flow from input to output. It does so by using a small voltage applied to the base (input) terminal of the device to control the current flow from collector to emitter (output). The base current is amplified by the current gain, β, of the transistor.

In other words, the output current from the collector of the KSB772YSTU device is controlled by the input current applied to the base of the device. The output current is significantly higher than the input current and is determined by the ratio of the current gain of the device. This amplification of current allows the use of low voltage systems to switch higher voltage loads.

KSB772YSTU is a general purpose NPN transistor designed for switching and amplifying applications. It offers excellent electrical performance in low voltage, high speed switching applications and is packaged in a very small SOT-23 package. It is ideal for use in audio circuits, power switching and in many other general purpose circuits.
