Covering the 2SA1767, this compact 39.8 KB PDF is listed as a schematic yet named with a JIS PNP bipolar transistor number, so its content is a device datasheet. The _E suffix is typical of English editions of Japanese maker documents, though the brand is not given. Consult it for maximum ratings, electrical characteristics, package outline and the marking code, which is the usual way to identify tiny SMD transistors on a board before ordering a replacement.
