Pinout

The STF28NM50N is a N-channel MOSFET in a TO-220FP package with 3 pins:
1. Gate (G) – Controls the switching operation.
2. Drain (D) – Connects to the load (high-voltage side).
3. Source (S) – Ground/reference terminal.
Key Features:
- 500V drain-source voltage (VDS).
- 28A continuous drain current (ID).
- Low on-resistance (RDS(on) = 0.085Ω).
- Suitable for switching applications (e.g., power supplies, motor control).
The TO-220FP package has a fully plastic body (no metal tab), improving isolation.
