PDF datasheet material for the 2SD1194 transistor, about 138 KB, catalogued here under schematics. The 2SD prefix comes from the Japanese JIS numbering scheme and indicates an NPN bipolar part for low-frequency circuits. When a device of this kind has gone short in a driver or output stage, the sheet helps you read the correct leg order and the limits a replacement must meet. Confirm voltage, current and dissipation ratings, and the package, before ordering a cross-reference part.
