Silicon Carbide Diodes

ROHM Semiconductor's SCS1xxAGC series of high-performance silicon carbide (SiC) Schottky barrier diodes (SBD) are now available. This new class of SiC diodes offers industry-leading low forward voltage and fast recovery time, leading to improved power conversion efficiency in applications such as PFC/power supplies, solar panel inverters, uninterruptible power supplies, air conditioners and others.

The SCS1xxAGC series maintains low forward voltage over a wide operating temperature range which results in lower power dissipation under actual operating conditions. For example, the 10 A rated part has a VF of 1.5 V at 25°C and 1.6 V at 150°C. Low VF reduces conduction loss while the ultra-short reverse recovery time (15 ns, typical) enables high-speed switching and minimizes switching loss.

With the acquisition of SiCrystal AG, ROHM Semiconductor possesses total manufacturing capability for SiC semiconductors from ingot formation to power device fabrication. This allows the rapid development of advanced products and complete control of raw materials for industry leading reliability and quality.
