A 48.1 KB PDF covering the 1T413 transistor, catalogued as a schematic entry. Its designation follows the Soviet system, with 1T identifying a germanium device of the kind used in older domestic and professional electronics. The document lists pinout, voltage and current limits and gain figures that help when measuring a transistor out of circuit or searching for a substitute. Take care with soldering heat on germanium parts, and confirm any grade letter on the component against the values given in the sheet.
