Brief 13.0 KB PDF datasheet for the 2SA1012 from UTC, that is Unisonic Technologies, which manufactures this transistor number among others. Following JIS convention the 2SA prefix denotes a PNP bipolar transistor. Expect concise ratings, characteristics and pinout specific to the UTC version. It is most useful when the part on the board carries UTC branding, because lead order and specifications can differ slightly between vendors. Check the marking first, then use the sheet for testing or replacement.
