BC547 Transistor(Pack of 5) The BC547 transistor is a versatile negative-positive-negative (NPN) transistor that can be used for a multitude of purposes. It acts as the active component for switches and amplifiers when used alongside electronic components like resistors, coils, and capacitors. As with all NPN transistors, this transistor features an emitter terminal, a base or control terminal, and a collector terminal.The BC547 transistor is classified as a bipolar junction transistor (BJT), and there exist other types of transistors as well. For example, the junction field-effect transistor (JFET) features a single junction, while the metal oxide field-effect transistor (MOSFET) doesn't have any junctions at all. During the design and manufacturing of transistors, their characteristics can be predefined and achieved.The negative (N)-type material inside the NPN transistor contains an excess of electrons while the positive (P)-type material has a deficiency of electrons, both due to the doping process. This type of transistor is commonly used in general-purpose switching and amplification and is part of the BC847/BC547 series of 45 V, 100 mA NPN general-purpose transistors.

BC557 PNP Transistor - (Pack of 5) A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. The BC557 (RM0385) is a PNP transistor and a heavy-duty drop-in replacement for a 2N2222 or 2N3906. The three terminals of a bipolar transistor are called the emitter, base, and collector. A small current into the base controls a large current flow from the collector to the emitter. The current at the base is typically one-hundredth of the collector-emitter current. Moreover, the large current flow is almost independent of the voltage across the transistor from collector to emitter. read our blog explaining the bc547 transistor pinout, which provides comprehensive information about the BC547 transistor, covering its role as a switch, working states, circuit diagrams, pin diagram.

TIP122 Darlington NPN Transistor - (Pack of 5) The TIP122(RM0387) is an NPN Epitaxial Darlington Transistor. Mainly used for Medium Power Linear Switching Applications and Complements to TIP125/126/127. In electronic, the Darlington transistor (often called a Darlington pair) is a compound structure consisting of two bipolar transistors (either integrated or separated devices) connected in such a way that the current amplified by the first transistor is amplified further by the second one. This configuration gives a much higher common/emitter current gain than each transistor taken separately and, in the case of integrated devices, can take less space than two individual transistors because they can use a shared collector. Integrated Darlington pairs come packaged singly in transistor-like packages or as an array of devices (usually eight) in an integrated circuit.
