Generally, BJTs are significant electronic components that work as basic building blocks within modern electronic circuits. These transistors are categorized into PNP and NPN transistors. In ICs or discrete components, thousands to millions of transistors are incorporated. It is essential to note that the electron movement is much faster & better as compared to the hole movement, so this is the reason to use an NPN transistor over a PNP transistor in many applications. These transistors are … [Read more...]

The BD140 PNP transistor was manufactured originally by Phillips and rated at 160MHz for use in particular audio applications. After that, these transistors were cloned simply by other electronic manufacturer companies like ON Semi, ST, Samsung, etc. Generally, there are well-known medium power PNP transistors available like BD136 & BD140 which are used in various electronic circuits. This article provides brief information on the BD140 Transistor, pinout, specifications, circuit, and its … [Read more...]

The BC548 is an NPN epitaxial silicon transistor that was created with the metal-cased BC108 family transistors. This transistor is a successor to the BC238 transistor & different from the BC108 transistor in the package shape. The specifications of the BC548 transistor are the same or exceed the BC148, BC238 & BC108. So this transistor is a suitable alternative within any circuit that is designed for the older BC148 or BC108. The BC548 transistor is generally used in American & … [Read more...]

The transistor is one of the significant semiconductor components used in almost every electronic device to regulate or control electronic signal flow. The transistor is a kind of semiconductor device, used for conducting & insulating electric current (or) voltage. Transistors are available in two types; PNP and NPN. Generally, a transistor includes three terminals or layers that are made with semiconductor material to carry a current. Transistors are utilized in a broad range of electronic … [Read more...]

The transistor is a semiconductor device that includes three terminals like emitter, base, and collector. The main function of the transistor is for switching and amplifying the base signal. But at present, these are frequently used within embedding integrated circuits. These transistors are available in two types PNP and NPN. In PNP transistors, the majority of charge carriers are holes whereas in NPN-type transistors, the majority of charge carriers are electrons. In transistors, the most … [Read more...]
