Datasheet PDF, 170 KB, for the semiconductor numbered 2SC2705, placed in the schematic listing. Under JIS naming, the 2SC prefix marks an NPN transistor. The name gives no package, manufacturer or variant details. Technicians typically consult such pages for pin diagrams, electrical limits and gain ranges when testing a shorted or open transistor and selecting an equivalent. It opens in any standard PDF reader. Compare the printed marking on the part with the document before relying on its values.
