Reference document for the 2N7002MTF, a 205 KB PDF stored with schematics. The base number 2N7002 is a well-known small-signal N-channel MOSFET, and the MTF letters are an ordering suffix, likely indicating packaging or tape format; the name does not explain it further. Technicians use this sheet to confirm gate, drain and source pins, threshold voltage and on-resistance when testing or replacing these tiny switches around power sequencing and signal level-shifting circuits on motherboards.
