PDF of 184 KB bearing the part number 2SD1410A, kept in the schematic category but best treated as the transistor's datasheet, with the A suffix denoting a variant of the 2SD1410. The 2SD prefix, under Japanese JIS rules, means an NPN bipolar transistor for low-frequency use. Look here for ratings, pin assignments and package dimensions before replacing a shorted device. Do not swap in the plain 2SD1410 without checking its limits, and expect the marking D1410A on the part.
