Ebers–Moll model for an NPN transistor. [28] I B, I C and I E are the base, collector and emitter currents; I CD and I ED are the collector and emitter diode currents; α F and α R are the forward and reverse common-base current gains.

BC108 family transistors from various manufacturers (ITT, CEMI, SGS-ATES, Siemens)The BC107, BC108 and BC109 are general-purpose low power silicon NPN bipolar junction transistors found very often in equipment and electronics books/articles from Europe, Australia [1] and many other countries from the 1960s.

The 2N3904 is an NPN transistor that can only switch one-third the current of the 2N2222 but has otherwise similar characteristics. The 2N3904 exhibits its forward gain (beta) peak at a lower current than the 2N2222, and is useful in amplifier applications with reduced I c , e.g., (gain peak at 10 mA for the 2N3904 but 150 mA for the 2N2222).
The BC548 is a part of a family of NPN and PNP epitaxial silicon transistors that originated with the metal-cased BC108 family of transistors.The BC548 is the modern plastic-packaged BC108; [6] the BC548 article at the Radiomuseum website [7] describes the BC548 as a successor to the BC238 and differing from the BC108 in only the shape of the package.
The 2N3904 is a common NPN bipolar junction transistor used for general-purpose low-power amplifying or switching applications. [1] [2] [3] It is designed for low current and power, medium voltage, and can operate at moderately high speeds. It is complementary to the 2N3906 PNP transistor. Both types were registered by Motorola Semiconductor in ...

The 2N3055 is a silicon NPN power transistor intended for general purpose applications. It was introduced in the early 1960s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mid-1970s. [1]
