  • 高效功率转换器(得益于低前向导通和开关损耗)
  • 与双二极管高功耗集成,降低了PCB尺寸
  • 显著降低了功率转换器尺寸和成本。
  • 自然的稳定性确保了超高的可靠性

1200 V SiC diodes deliver superior efficiency and robustness

Our range of 1200 V silicon-carbide (SiC) JBS (Junction Barrier Schottky) diodes meets designers' needs for superior efficiency, low weight, small size, and improved thermal characteristics for performance-oriented applications.

Offering the best-in-class forward voltage (lowest VF) and state-of-the-art robustness, our 1200 V SiC diodes provide extra freedom to achieve high efficiency and reliability with lower current rating and therefore lower cost, while reducing operating temperature and extending application lifetime. They ensure a perfect fit in every switch mode converter and inverter - SMPS, UPS, solar, motor drives- where extreme power density and efficiency are needed.

Covering current ratings from 2 to 40 A, our 1200 V SiC diode family includes industrial-dedicated as well as automotive-qualified devices in surface-mount DPAK HV (high-voltage) and D²PAK, or through-hole TO-220AC and TO-247LL (long-lead) packages.

ST's 1200V SiC allows reaching the highest standards and smallest form factor.
