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.

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.
