Typical Applications
STFU13N80K5 is suitable for 6 applications: Switch-Mode Power Supplies (SMPS), Power Factor Correction (PFC), High-Voltage DC-DC Converters, LED Lighting Drivers, Solar Inverters, Industrial Power Supplies.
Switch-Mode Power Supplies (SMPS)
The STFU13N80K5 is ideal for SMPS due to its 800V breakdown voltage and low on-resistance. In a typical flyback converter, the MOSFET switches at high frequency to transfer energy from primary to secondary. Its low gate charge (38 nC) enables fast switching, reducing switching losses. The TO-220FP package allows easy heatsinking, and the device can handle the high voltage spikes present in flyback topologies. Compared to IGBTs, the MOSFET offers faster switching and lower conduction losses at moderate power levels, improving overall efficiency.

Power Factor Correction (PFC)
In boost PFC circuits, the STFU13N80K5 operates at high voltage (up to 800V) and high frequency. Its low RDS(on) of 0.29 ohm minimizes conduction losses, while the fast body diode (trr=330 ns) reduces reverse recovery losses. The device's high dV/dt capability ensures reliable operation in continuous conduction mode. The TO-220FP package simplifies thermal management, allowing the MOSFET to dissipate up to 35W. This makes it suitable for PFC stages in server power supplies and industrial drives, where high efficiency and power density are critical.

Key Differentiators
- Isolated TO-220FP package (vs STF13N80K5 (TO-220))
- Higher voltage rating than some competitors (vs IPP60R099CP (600V))
- Lower on-resistance than typical 800V MOSFETs (vs FCP13N80 (0.29 ohm))
Design Notes
The STFU13N80K5 in TO-220FP package has a junction-to-case thermal resistance of 3.5°C/W. At 35W dissipation, the junction temperature rise is 122.5°C above case temperature. Ensure adequate heatsinking to keep the junction below 150°C. Use thermal compound and a proper heatsink with sufficient surface area and airflow.
For the TO-220FP package, the tab is isolated, so no additional insulation is needed when mounting to a heatsink. However, ensure the gate drive traces are short and direct to minimize parasitic inductance. Place a gate resistor (typically 10-100 ohm) close to the gate pin to dampen oscillations. Use a low-ESR ceramic capacitor (e.g., 100nF) near the drain for high-frequency decoupling.
Do not exceed the maximum gate-source voltage of ±30V. Use a gate driver with appropriate voltage clamping if necessary. Also, ensure the drain-source voltage does not exceed 800V, especially during switching transients. Implement a snubber circuit (RCD or RC) across the drain-source to limit voltage spikes caused by leakage inductance in flyback transformers.
