BC81825MTF Transistors - Bipolar (BJT) - Single

BC81825MTF is a single transistor and belongs to the family of bipolar junction transistors (BJTs). It is a small signal general-purpose NPN transistor and is used in various applications such as amplifier, driver, switching and others. It is made using a unique silicon-germanium channel enabling the transistor to operate at a wide range of temperatures right up to +175°C.

Basic Structure

BC81825MTF is a three-terminal voltage-controlled device. It has two p-type silicon layers and one n-type germanium layer. The base is the middle layer between the two silicon layers. Then, there is an emitter at the bottom and the collector at the top. The collector and the emitter are connected to the external circuit.

Working Principle

When we connect a voltage to the base terminal of the transistor, it causes the electrons to be drawn from the emitter region towards the base. This process is called \'forward biasing\'. This, in turn, causes current to flow through the transistor and the collector-emitter region. The main difference between a typical bipolar junction transistor and a BC81825MTF transistor is the ability of the BC81825MTF to handle higher temperatures. The silicon-germanium channel of BC81825MTF is uniquely designed to be able to operate at a wide range of temperatures up to +175°C. This makes BC81825MTF ideal for applications that require sustained performance at higher temperatures.
