60 V, 200 mA, 5 Ohm — the small-signal MOSFET baseline
The STMicroelectronics 2N7002 is an N-channel enhancement-mode MOSFET from the STripFET™ series, built for low-power switching and signal-level loads. The 2 nC gate charge at 5 V keeps the switching drive current low — a GPIO pin can drive it directly without a buffer.
SOT-23-3 footprint and temperature range
The 2N7002 comes in the SOT-23-3 package (also referred to as TO-236-3 or SC-59), a three-lead surface-mount footprint that is a de facto standard for small-signal MOSFETs.
