Pinout
The BSS84 is a P-channel MOSFET with 3 pins (TO-236/SOT-23 package).
Pin Functions:
1. Gate (G): Controls the MOSFET's conductivity.
2. Drain (D): Connects to the load (negative side for P-channel).
3. Source (S): Connects to the supply voltage (positive side).
Key Features:
- VDS: -50V (max)
- ID: -130mA (max)
- Low threshold voltage (~-1V).
Commonly used for switching and amplification in low-power circuits.
