Transistor data in a 215 KB PDF named 2SC3376, catalogued as a schematic. The 2SC prefix belongs to the Japanese JIS scheme and marks an NPN device intended for high-frequency circuits, so the file should cover one component. Expect maximum ratings, electrical characteristics, gain ranks and a dimensioned package outline with pinout. It helps when measuring junctions with a multimeter or sourcing a compatible replacement. Verify that the code printed on the original transistor matches this number before use.
