Component documentation for the 2SC3669 in PDF format, 192 KB in size. The 2SC prefix in Japanese JIS numbering indicates an NPN bipolar transistor, and the bare part-number name suggests a datasheet rather than a full circuit diagram. Expect maximum ratings, characteristic curves and outline dimensions. When a transistor of this type fails short, the sheet helps confirm pinout for in-circuit diode tests and guides the choice of a substitute with equal or higher voltage and current limits.
