Pinout
The 2N7002 is a small-signal N-channel MOSFET with 3 pins in a SOT-23 package:
1. Gate (G) – Controls the MOSFET's conductivity (threshold ~0.8–3V).
2. Drain (D) – Connects to the load (max 60V).
3. Source (S) – Ground reference (connected to the substrate).
Key Features:
- Low-power switching (max 300mA drain current).
- Fast switching speed, suitable for logic-level applications.
Common uses include signal switching, level shifting, and low-current loads.
