Reference sheet in PDF form for the 2SA1593 transistor, 156 KB in size. The name gives only the part number, with no device or board details. In JIS coding, 2SA designates a PNP high-frequency bipolar transistor. Expect maximum ratings, hFE classes, characteristic curves and the package drawing. Before substituting a part, compare its voltage, current and power limits and its pin order with this sheet, since lead arrangements differ between packages. Read any suffix letter on the original part, which often indicates the gain grade.
