PDF document, 39.0 KB, for a part named 2SC4627J, with an extra _E tag in the name whose meaning is not stated. It is indexed as a schematic but appears to be a transistor datasheet. The 2SC prefix marks an NPN bipolar device under JIS numbering, and the J letter is part of the stated part number. Use it to check pinout, case outline and electrical limits. Make sure the suffix printed on the board part matches exactly, since suffixed variants can differ.
