The company was acquired by ON Semiconductor in 2016 and its products and technologies continue to be developed and sold under the ON Semiconductor brand. 2N3906 is also a very popular PNP transistor which is also designed for general purpose switching, amplification and other general applications and its NPN complementary transistor is 2N3904. The company was known for its innovation in the development of the first commercial transistor and for its contributions to the advancement of the integrated circuit technology.įairchild became a leading supplier of power semiconductors, analog and mixed-signal integrated circuits, and other semiconductor products. I keep a hundred or so of each type on hand to play with. They have good gain and frequency characteristics for most analog or digital projects, but most significant to me: they are dirt cheap. Bipolar (BJT) Transistor PNP 40 V 200 mA 250MHz 625 mW Through Hole TO-92. 2n2222 Equivalent 2n2222 Equivalent2N2222A Equivalents 2N2907 (PNP), 2N3904 (PNP), 2N3906 (PNP), BC637, S9014, BC148, 2N4403, MPS2222, PN2222, KN2222.

Fairchild Semiconductor was a pioneering semiconductor company that was founded in the late 1950s. The 2N3904 (NPN) and 2N3906 (PNP) are my favorite go-to small-signal transistors.
