The BUX85 is a general purpose, PNP, bipolar junction transistor (BJT) that is capable of switching a large amount of current over a significant voltage drop. It is designed for use in medium and low power switching applications, as well as high voltage and/or current gain applications. In addition to its medium to low power switching capability, the BUX85 is also designed with features that enhance its use as a high voltage and/or current gain device.

The BUX85 is a single, PNP, bipolar junction transistor (BJT), in the TO-92-style plastic package. It is designed to operate with a maximum voltage rating of 40 Volts and a maximum collector current of 800 milliamps. It is also capable of handling collector-emitter junction voltages of up to 100 Volts. It has a moderate switching speed and a good thermal dissipation characteristic.

The BUX85 has two modes of operation: the common base mode and the common emitter mode. In the common base mode, the input signal is applied to the base of the transistor (the input terminal) and the output is taken from the collector. This type of operation is ideal for large current or voltage gains, or for making high speed switches. In the common emitter mode, the input signal is applied to the emitter of the transistor (the output terminal) and the output is taken from the collector. This type of operation is better suited for small current or voltage gains and for switching lower voltages. The BUX85 is rated for operation at temperatures up to 150°C.

The BUX85 can be used in a wide variety of applications, including medium and low power switching, signal amplification, voltage regulation and current buffering. It is often used as a power switch and to control the current flow in circuits. Additionally, it can also be used as a complement to the NPN transistor (2N3904, for example) in complementary circuits. Its versatility makes it suitable for use in a variety of electronic devices, such as microcontrollers, logic circuits, power supplies and motor control circuits.

The BUX85, as with other BJT transistors, works by using the base-emitter junction to control the current flow between the collector and the emitter. When a small current is applied to the base terminal, a large current is allowed to flow from the collector to the emitter. This process is called "amplification" and is used to increase the voltage or current gain of the transistor. The gain of a transistor is dependent on several factors, such as the type of circuit it is used in, the amount of current applied to the base and the voltage applied to the base-emitter junction.

The BUX85 is an ideal device for use in medium and low power switching applications, where its high voltage and current gain capabilities are best exploited. It is also used frequently in analogue and digital circuits, as its moderate switching speed makes it well suited for different types of switching applications. Its thermal dissipation characteristic allows it to be used in high temperature applications, as it is designed to operate at temperatures up to 150°C.

Overall, the BUX85 is a versatile and reliable BJT transistor that is suitable for use in a wide variety of applications. Its broad range of features make it a popular choice for use in medium and low power switching, signal amplification, voltage regulation and current buffering. The BUX85 is commonly employed in analogue and digital circuits, and is rated for operation at temperatures up to 150°C.
