Available from multiple manufacturers including onsemi, Infineon, Diodes Incorporated, NXP, and others, it provides 60V drain-source breakdown voltage, 115mA continuous drain current, and 7.5\u03a9 maximum on-resistance at VGS=10V. The low gate threshold voltage (1.0V to 2.5V) enables direct drive from 3.3V and 5V microcontroller GPIO pins without additional gate drive circuitry. Housed in a compact SOT-23-3 package, the 2N7002 is ideal for low-power switching, level shifting, and load control in virtually every category of electronic design. Its extremely low cost ($0.027 at volume) and broad multi-source availability make it a default choice for general-purpose MOSFET switching.","working_principle":"

      Enhancement-Mode Operation<\/h3>\n

      The 2N7002 is an enhancement-mode MOSFET, meaning it is normally off (non-conducting) when VGS = 0V. When the gate-to-source voltage exceeds the threshold voltage (VGS(th), typically 2.1V), an inversion layer forms in the P-type body region beneath the gate oxide, creating a conductive N-type channel between drain and source. Increasing VGS further enhances the channel, reducing on-resistance (RDS(on)) and increasing drain current capability.<\/p>\n\n

      Switching Behavior<\/h3>\n

      The low gate charge (approximately 50pC) enables fast switching transitions, limited primarily by the gate driver's current capability and the gate resistance. Turn-on time is determined by how quickly the gate capacitance can be charged above VGS(th), while turn-off requires discharging the gate below threshold. The low capacitance (Ciss ~50pF) makes switching efficient even at moderate frequencies.<\/p>\n\n

      Body Diode<\/h3>\n

      Like all vertical MOSFETs, the 2N7002 has an inherent P-N junction (body diode) between source and drain. This diode conducts when VDS is negative (source higher than drain), providing a path for inductive kickback currents in switching applications. The body diode has a typical forward voltage of 0.9V to 1.2V.<\/p>\n\n

      On-Resistance Characteristics<\/h3>\n

      RDS(on) varies significantly with gate drive voltage. At VGS=10V, RDS(on) is specified at 7.5\u03a9 maximum. At VGS=4.5V (typical 3.3V logic high), RDS(on) increases. At VGS=2.5V, it increases further, approaching the threshold region. For reliable low-RDS(on) switching, a gate voltage of 4.5V or higher is recommended.<\/p>","pin_description":"\n
