Additionally, the transistor has a good frequency response, with a cut-off frequency (fT) of 12MHz. which makes it suitable for low-noise applications. Furthermore, the BUT12ATU is extremely reliable and has a long lifetime, making it ideal for semi-permanent installations. It also has an exceptionally low noise figure of 1.2 dB.

BUT12ATU Application Fields and Working Principles

The BUT12ATU can be applied in many circumstances, such as in discrete amplifier and switching circuits, as well as in integrated circuits. In discrete amplifier and switching circuits, the device may be configured to act as a current source, voltage regulator or in an active mode. In active mode, the transistor may act as either a common emitter or common collector amplifier. As a common emitter amplifier, the transistor is biased in the forward active region, and the collector current is proportional to the base current. As a common collector amplifier, the transistor is biased in the reverse active region, and the collector current is proportional to the collector voltage. In integrated circuits, the BUT12ATU is used in logic circuits, analog functions, as an oscillator and in power management circuits. Furthermore, the device can be used in special purpose applications, such as electromagnetic interference (EMI) shielding.

In addition to being used in circuits, the BUT12ATU can be used for sensing. The transistor has a built-in thermistor, allowing it to detect heat, as well as to sense current, voltage and impedance. This feature makes it useful in, for example, overcurrent protection circuits. Furthermore, the transistor can be used in touch-sensitive switches, as it can detect very small voltages and currents. Finally, the BUT12ATU also has a photovoltaic mode, allowing it to be used as a photodiode or a phototransistor. This makes it useful in motion sensors, ambient light detectors, and light-sensing devices, such as nightlights.
