At 262 KB this is the largest file in the batch, a PDF for the 2SA1432 transistor, likely holding graphs and package drawings as well as the rating tables. The 2SA designation follows the Japanese JIS system for PNP transistors. Nothing else, such as maker or revision, is stated in the name. Use it to confirm lead order, safe operating limits and saturation behaviour when diagnosing a dead stage or matching a replacement. Read the absolute maximum ratings before considering a substitute part.
