1200V silicon carbide diodes offer efficiency and robustness
The diodes are fabricated in a process that creates extremely robust devices with the best-in-class forward voltage (lowest VF), giving circuit designers extra freedom to achieve high efficiency and reliability using diodes with lower current rating and therefore lower cost. This, ST says, makes SiC technology more accessible for cost-conscious applications including solar inverters, industrial motor drives, home appliances, and power adapters.
Performance-oriented applications that demand SiC for superior efficiency, low weight, small size, or best thermal properties can extend these advantages. The higher efficiency margin provided by their lower forward voltage drop (VF) delivers important benefits for automotive equipment such as On-Board Battery Chargers (OBC) and charging stations for Plug-In Hybrid or Electric Vehicles (PHEV/EV). Overall robust electrical performance ensures a perfect fit in telecom and server power supplies, high-power industrial Switched-Mode Power Supplies (SMPS) and motor drives, uninterruptible power supplies (UPS), and large solar inverters.
ST’s 1200V SiC diode family covers current ratings from 2A to 40A, including automotive-qualified devices, in surface-mount DPAK HV (High-Voltage) and D²PAK, or through-hole TO-220AC and TO-247LL (Long-Lead) packages. ST says it is the only supplier to offer 1200V SiC diodes in the D²PAK package. Pricing starts at $2.50 for the 10A STPSC10H12D in TO-220AC (1000).
