PDF reference for the 2SK2825, 301 KB in size and listed in the schematic section. The 2SK designation, from the Japanese JIS numbering system, belongs to N-channel FETs, so expect a datasheet with electrical specifications and a package drawing. It is handy for checking pin order before desoldering, comparing on-resistance and voltage ratings with a replacement, and understanding how the device should test in circuit. The name states nothing more, so verify the exact marking on the failed component first.
