PDF for the 2N6718, a 160 KB document filed under schematics with only the part number in the name. 2N-series numbers follow the American JEDEC registration, and this one belongs to a family of medium-power bipolar transistors, so expect ratings, characteristics and a package drawing. Technicians use it to confirm pinout, polarity and voltage and current limits when testing or replacing the device. Open it in any PDF reader and match the case style and printed code on the component to the sheet before ordering a substitute.
