Datasheet-style PDF of 38.9 KB for the 2SB1340, catalogued as a schematic. The Japanese JIS 2SB prefix marks PNP transistors designed for low-frequency circuits such as drivers and regulators. No other details are carried by the file name. When a board shows a shorted or open transistor at this position, the sheet lets you confirm which lead is which, read the breakdown voltage and current rating, and select an equivalent part that matches package and lead order.
