A 121 KB PDF for the 2N6027, filed as a schematic but most likely the device datasheet. The name gives no manufacturer, package or revision. Not every JEDEC 2N number is an ordinary bipolar transistor: the series also includes thyristor-type and other two-junction devices, so read the description on the sheet itself. It helps confirm terminal functions, operating parameters and limits before you test the part in circuit, replace it or check a timing or trigger stage.
