Pin Configuration (TO-220)
Looking at the front of the TO-220 package (facing the part markings, pins pointing down from left to right):
- Gate (G): Triggers the MOSFET on/off.
- Drain (D): Connected to the load (also connected to the metal heatsink tab).
- Source (S): Connected to the system ground or negative rail. [1]
