Component document for the 2SC3934, stored as a 50.5 KB PDF and carrying an _E suffix. Although indexed as a schematic, the 2SC designation follows Japanese JIS transistor numbering, which denotes an NPN device intended mainly for high-frequency use. Expect pin assignments, absolute maximum ratings, electrical characteristics and package drawings. Use it to identify a failed transistor, pick an equivalent with matching voltage, current and gain figures, and verify base, collector and emitter positions on the PCB footprint.
