Reference sheet for the 2SJ418 P-channel FET, supplied as a 128 KB PDF and indexed as a schematic. The 2SJ prefix follows Japanese JIS semiconductor naming, where the J letter marks a P-channel field-effect device. Nothing else about the part, such as manufacturer or case style, is stated in the name. A repair technician typically uses this document to check maximum drain-source voltage, continuous drain current and pinout, and to judge whether a substitute with similar or better ratings will fit the footprint.
