- Silicon carbide construction eliminates reverse recovery losses for high-frequency PFC and inverter stages
- 650V blocking voltage with 4A continuous rating handles universal AC-line rectification
- 1.55V maximum forward voltage reduces conduction losses versus standard silicon Schottky diodes
Applications
STPSC4H065DLF suits boost-stage power factor correction circuits, solar inverters, and industrial SMPS operating from 400V AC mains. Its SiC construction enables switching frequencies above 100 kHz without the reverse-recovery losses that degrade efficiency in silicon-only topologies. The D2PAK-4L (DFN4) package provides excellent thermal performance for continuous 4A operation in high-power density designs.

Frequently Asked Questions
How does STPSC4H065DLF improve efficiency in a boost PFC stage compared to a silicon fast-recovery diode?
STPSC4H065DLF uses silicon carbide technology, which provides near-zero reverse recovery charge (Qrr) at switching frequencies above 100 kHz. Eliminating Qrr losses reduces switching losses in the MOSFET and diode pair, improving converter efficiency by 1% to 2% in typical 650V boost PFC stages operating at 65 kHz to 200 kHz.
What continuous and peak current ratings does STPSC4H065DLF support in power supply designs?
STPSC4H065DLF is rated for 4A continuous forward current and a 38A non-repetitive peak surge current. The 38A surge capability protects the rectifier during startup transients and inrush events in PFC stages, while the 4A continuous rating suits single-phase mains rectification in 200W to 300W power supplies.
For which high-voltage applications is STPSC4H065DLF best suited given its 650V rating?
The 650V blocking voltage directly targets universal AC mains applications at 85V to 265V AC input, where peak rectified voltages reach 375V. Solar microinverters, electric vehicle on-board chargers, and server power supply PFC stages are prime uses, all benefiting from the SiC Schottky diode forward voltage of 1.55V maximum at full rated current.
How does the D2PAK-4L package of STPSC4H065DLF help manage thermal dissipation in high-power designs?
The D2PAK-4L (TO-263-4L) package provides a large exposed copper drain pad that interfaces directly with the PCB copper pour, achieving a junction-to-case thermal resistance below 5°C/W. This enables continuous 4A operation at ambient temperatures up to 70°C without an additional heat sink, making it practical for compact industrial SMPS designs.
