Largest of the _E series at 59.4 KB, the 2SC3936 PDF is catalogued as a schematic but is named like a transistor datasheet, with the suffix usually indicating an English edition. JIS 2SC numbers designate NPN bipolar transistors. The sheet should supply ratings, characteristics and the package outline, letting a technician identify pins, judge a suspected failure and pick an equivalent with adequate limits. Check the C3936 body marking and case type against the document before use.
