The smallest of this group at 23.0 KB, this PDF covers the 2sk2474, a JIS-numbered N-channel FET. Only the part number is given in the name, so maker, package and document edition remain unknown until opened. Such a brief sheet usually lists pinout and essential limits. It helps a technician identify gate, drain and source for a diode-mode check and confirm the voltage and current a replacement must handle. Compare the body marking on the board before relying on it.
