Slightly larger at 109 KB, this PDF covers the 2SK1419 and is listed among schematics, though it most likely holds a datasheet. The 2SK code in JIS semiconductor numbering marks an N-channel field-effect transistor. Specifics such as case style and ratings are not stated in the name. Use it to look up terminal assignment, maximum ratings and characteristic data, which are needed when confirming a shorted device and when sourcing an equivalent with equal or higher limits.
