As power electronics continue to evolve toward higher efficiency, greater reliability, and compact designs, Diotec Semiconductor steps forward with its latest innovation: the DIF170SIC049, a 1700V Silicon Carbide (SiC) MOSFET housed in a TO-247-4L package. This device is engineered to meet the rigorous demands of modern power conversion systems, offering a compelling combination of high voltage capability, low on-resistance, and fast switching performance.
Key Features:
Diotec’s DIF170SIC049 is tailored for applications where efficiency and thermal performance are critical. Its low RDS(on) minimizes conduction losses, while the Kelvin-source configuration enables faster switching with reduced gate bounce and EMI. This makes it ideal for both soft- and hard-switching topologies, whether used in a flyback converter or a three-phase inverter.
Moreover, the device’s high reverse breakdown voltage and robust thermal characteristics ensure long-term stability, even under demanding operating conditions. Designers can confidently integrate this MOSFET into systems requiring high voltage isolation, fast switching, and compact thermal management.
The DIF170SIC049 fits seamlessly into a wide range of power electronics applications, including:
| Parameter | Value |
| Drain-Source Voltage (VDSS) | 1700 V |
| On-State Resistance (RDS(on)) | Max 49 mΩ |
| Drain-Source Leakage Current (IDSS) | 100 µA |
| Gate-Source Voltage Range (VGSS) | -8 V to +22 V |
| Recommended VGS(on) | +18 V |
| Recommended VGS(off) | -4 V |
| Power Dissipation (Ptot) | 357 W |
| Peak Drain Current (IDM) | 150 A |
| Thermal Resistance (RthC) | 0.21 K/W |
| Operating Junction Temp (Tj) | -55°C to +175°C |
| Package | TO-247-4L |
With the DIF170SIC049, Diotec continues to push the boundaries of what’s possible in high-voltage power semiconductors. By leveraging the inherent advantages of SiC technology—including high thermal conductivity, low switching losses, and superior voltage handling—this MOSFET is poised to become a cornerstone in next-generation energy systems.
Whether you’re designing for renewable energy, transportation, or industrial automation, Diotec’s DIF170SIC049 offers the performance and reliability needed to drive innovation forward.
