Accessing knowledge base.

That top mark “7002” on a 3‑pin SMD package is very likely a 2N7002 N‑channel MOSFET (SOT‑23), commonly used for small‑signal switching and level‑shifting.
How to verify quickly:
  • Gate will be the pin that’s isolated (very high resistance to the others).
  • In diode‑test mode you’ll read a body‑diode between the other two pins; the remaining pin is the gate. Typical pinout for 2N7002 is 1=Gate, 2=Source, 3=Drain (confirm with your board traces).
