Pinout
Pin Functions:
1. Gate (G): Controls the MOSFET's switching.
2. Drain (D): Connects to the load (high-side switching).
3. Source (S): Connects to the power supply (typically V+).
Key Features:
- -30V drain-source voltage (VDS)
- -40A continuous drain current (ID)
- Low on-resistance (RDS(on) ≈ 8.5mΩ at VGS = -10V)
- Logic-level gate drive (VGS ≥ -4.5V).
Commonly used for power switching, load control, and DC-DC conversion.
