Bipolar transistors
(8 411)Bipolar transistors are semiconducting electronic components used to amplify or switch the signal. They consist of three layers of a semiconductor - base, emitter and collector. The smaller electric current, flowing between the base and the emitter, controls the higher current between the emitter and the collector. Bipolar transistors can be divided into PNP and NPN (with opposite directions of voltages and currents), which informs about types of semiconductors used to create given components. Silicon and germanium are the most popular when it comes to the materials used. Bipolar transistors are selected in accordance with the basic parameters of elements such as collector current, collector-emitter voltage and power loss values. Moreover, the assembly method should also be taken into consideration, depending on the needs and preferences, elements for THT and SMD montage are available. When it comes to applications, bipolar transistors can be used in logic circuits, electronic amplifiers, temperature sensors and logarithmic transducers.
Bipolar transistors in the TME offer
The TME electronic store distributes bipolar transistors with a wide range of applications. The online offer of TME includes PNP and NPN transistors with different values of collector current and collector-emitter voltage. Filters in the searching engine also allow to divide them due to power loss and mounting variant (THT / SMD / screw). A special type of transistors are Darlington transistors, which are amplifier circuits, based on two connected bipolar transistors. In this type of transistors collector currents are added, which makes the transistor amplify the signal more strongly than in the case of two separate subassemblies. After you select the necessary products, the store also provides convenient packaging, such as rollers, tubes or tapes.
