Part documentation for the 2SK2914 in PDF form, 396 KB, placed in the schematic section of the index. Apart from the part number the name states nothing, so details such as maker and revision must be read from the document itself. The 2SK prefix follows JEITA registration and marks an N-channel field-effect transistor. During repair it helps identify pins for diode-mode testing, confirm ratings for a short or overheating fault and pick an equivalent. Verify the component marking before trusting the data.
