Compact 29.9 KB PDF for the 2SA2063 transistor, indexed as a schematic but serving as component data. By JIS convention, the 2SA prefix identifies a PNP transistor of the high-frequency class. A short sheet like this typically summarises the pinout, package, voltage and current limits and hFE range. Technicians use it to confirm terminal order before measurement or replacement and to check that a substitute meets the original ratings; verify the body marking on the part before relying on it.
