Freigelegter Transistorchip eines 2N3055ers. Bipolarer NPN-Transistor, 15A, 60V, Hersteller: ST, Kaufdatum: 2007. Attribution: Stefan Riepl.
A Mullard OC200 and two OC45 transistors from the early 1960s. They show some of the variety of SO-2 packages used at this time. From the top, the OC200 is an early silicon PNP transistor in an aluminium can. Central is a black OC45 germanium transistor in a black-painted glass package. Bottom is an OC45 in a clear glass and blue putty package, with rubber sleeve.
