PDF datasheet for the 2SA1327A, around 176 KB, where the A suffix marks a variant of the 2SA1327 type. In JIS numbering, 2SA denotes a PNP transistor intended for high-frequency circuits. Look in the document for lead identification, package drawing, maximum ratings and electrical characteristics. Variant letters can mean different voltage ratings or packaging, so match the exact marking on the board before using these figures for testing or for deciding on a cross-referenced substitute.
