Reference sheet for the 2SA1814 transistor, supplied as an 84.8 KB PDF. The 2SA designation in Japanese JIS numbering means a PNP bipolar device, so the document should list its absolute maximum ratings, electrical characteristics and package drawing. It is handy when a failed part has to be identified or matched, or when you need the emitter, base and collector order to probe the device in circuit. Check the marking printed on the component against the sheet before ordering parts.
