Revision 1 of a document for the 2SA1774, as the rev1 token in the name indicates, supplied as a 97 KB PDF and filed under schematics. The 2SA prefix in the JIS system identifies a PNP bipolar transistor, so this is a part datasheet. It should list pin order, package dimensions, ratings and gain ranks. When servicing, check the marking on the component against it, confirm orientation on the footprint, and confirm a substitute meets every listed limit.
