Pinout

The STF3NK80Z is a N-channel MOSFET in a TO-220FP (isolated) package with 3 pins:
1. Gate (G) – Controls the switching operation.
2. Drain (D) – Connects to the load (high-voltage side).
3. Source (S) – Connects to ground (low-voltage side).
Key Features:
- 800V drain-source voltage (VDSS).
- 2.7A continuous drain current (ID).
- Low on-resistance (RDS(on)) for efficient switching.
- Fast switching for power applications (e.g., SMPS, motor control).
The TO-220FP variant has an isolated tab, allowing direct mounting to a heatsink without insulation.

Application

The STF3NK80Z (N-channel MOSFET, 800V, 3A) is commonly used in:
1. Switching Power Supplies – AC-DC converters, flyback designs.
2. Lighting Systems – LED drivers, ballast controls.
3. Motor Control – Low-power motor drives.
4. Industrial Electronics – Relays, solenoids, and inverters.
5. Consumer Electronics – Adapters, chargers.
Its high voltage rating and efficiency make it suitable for energy-efficient and compact designs.

Package

The STF3NK80Z is a TO-220FP (isolated) package type. This package features a fully plastic body with a thermal pad for heat dissipation, providing electrical isolation between the device and the heatsink. It's commonly used for power MOSFETs in applications requiring insulation and efficient thermal management. The TO-220FP is similar to the standard TO-220 but with an insulated mounting option.
