Key Features
- Silicon carbide (SiC) Schottky construction eliminates reverse recovery charge, enabling switching frequencies above 100 kHz without efficiency penalty
- 650 V blocking voltage with 1.55 V maximum forward voltage delivers superior efficiency in bridgeless PFC and boost converter stages
- Single-diode PSSO-N4 package with cathode case connection simplifies PCB layout and thermal management in high-voltage power supplies
Applications
STPSC6H065DLF is designed for high-efficiency power conversion stages including bridgeless power factor correction (PFC) circuits, hard- and soft-switched DC-DC converters, and solar inverter boost stages operating up to 650 V. Its SiC Schottky technology eliminates reverse recovery losses that plague silicon diodes at frequencies above 50 kHz, directly improving total system efficiency. Industrial SMPS, EV on-board chargers, and motor drive rectifier stages benefit from its combination of low forward drop and high-temperature operation capability.

Frequently Asked Questions
How does the SiC construction of STPSC6H065DLF eliminate reverse recovery losses compared to silicon rectifiers?
Silicon carbide Schottky diodes have no minority-carrier injection, so the reverse recovery charge Qrr is effectively 0 nC across the full 25 °C to 175 °C junction temperature range. In contrast, silicon fast-recovery diodes can exhibit Qrr values of 50 nC to 500 nC at 650 V, causing significant switching losses at frequencies above 50 kHz. Eliminating Qrr allows STPSC6H065DLF to operate in PFC stages at 100 kHz to 200 kHz without the reverse recovery spike that normally requires larger gate resistors and snubbers.
What is the maximum forward voltage of STPSC6H065DLF and how does it affect conduction losses in a 6 A rectifier stage?
The maximum forward voltage VF is 1.55 V at 6 A and 25 °C. At full rated current of 6 A, conduction power dissipation is approximately 9.3 W, which is competitive with silicon ultra-fast diodes at this voltage class. The low VF directly reduces junction temperature rise and extends MTBF in continuous conduction mode boost stages carrying 4 A to 6 A average current.
Which power supply topologies are best suited to STPSC6H065DLF given its 650 V rating?
STPSC6H065DLF is optimized for 400 V DC bus applications typical of single-phase bridgeless PFC front-ends, AC-DC flyback converters with 230 VAC input, and interleaved boost PFC stages. The 650 V blocking voltage provides a safe margin of at least 50 V above the peak 400 V rail, accommodating line transients and resonant voltage spikes in LLC converters up to 3 kW.
How does STPSC6H065DLF compare to a standard silicon Schottky diode for a 650 V EV charger design?
At 650 V, silicon Schottky diodes are impractical because their leakage current rises sharply above 200 V, resulting in excessive reverse power loss at elevated temperatures. STPSC6H065DLF uses SiC technology that maintains reverse leakage below 10 µA at 650 V and 150 °C junction temperature, making it the preferred choice for on-board EV chargers and industrial AC-DC converters requiring both 650 V standoff and high switching frequency above 100 kHz.
