2N2905

Schematic .pdf 55.3 KB Shared

Reference sheet for the 2N2905 PNP silicon transistor, a 55.3 KB PDF placed in the schematic category. The 2N2905 is a general-purpose switching and amplifier device commonly found in a TO-39 metal can, where the case is normally connected to the collector. Repair work benefits from its pinout diagram, maximum collector-emitter voltage, current limit and gain values when testing a suspect transistor or sourcing a replacement. Verify the marking on the original component, since plastic lookalikes may carry different lead assignments.
