SiC Diodes

ST’s silicon carbide diodes range from 600 to 1200 V – as single and dual diodes – and feature unbeatable reverse recovery characteristics and improved VF. Available in a wide variety of packages, from D²PAK to TO-247 and the insulated TO-220AB/AC, they offer great flexibility to designers looking for efficiency, robustness and fast time-to-market.

ST’s SiC Schottky diodes show a significant power-loss reduction and are commonly used in hard-switching applications such as high-end-server and telecom power supplies, while also intended for solar inverters, motor drives and uninterruptible power supplies (UPS).
ST’s automotive-grade 650 and 1200 V SiC diodes – AEC-Q101-qualified and PPAP capable – feature the lowest forward voltage drop (VF) on the market, for optimal efficiency in electric vehicle (EV) applications.

Main characteristics: 
   - High efficiency of the power converter (thanks to low forward conduction and switching losses)
   - High power integration with dual diodes for reduced PCB form factor
   - Significant reduction of power converter size and cost
   - Low EMC impact, for simplified certification and reduced time-to-market
   - Natural high robustness ensuring very high reliability

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.
