Here is a 122 KB PDF for the 2SA1696, a semiconductor numbered under the Japanese JIS system and listed among schematics, though a part-coded file like this is normally a component datasheet. A 2SA designation means a PNP transistor aimed at high-frequency work. Beyond the part number, the name gives no details. Open it in any PDF viewer to check pin layout, package dimensions and electrical limits, which helps when testing a suspect device with a meter or sourcing a compatible substitute.
