2. Drain (D) – Connects to the load (handles up to 500V, 20A).
3. Source (S) – Connected to ground (common return path).
Key Features:
- 500V VDSS, 20A ID (at 25°C).
- Low on-resistance (RDS(on) ~0.27Ω).
- Used in power supplies, inverters, and motor drives.
*Package:* TO-247AC (3-pin, tab is electrically connected to the Drain).
