ROHM Semiconductor (San Diego, CA) has announced the SCS1xxAGC series of silicon carbide (SiC) Schottky barrier diodes (SBDs). The SiC diode maintains low forward voltage over a wide operating temperature range, which results in lower power dissipation under actual operating conditions. The 10A rated part, for example, has a VF of 1.5V at 25 °C and 1.6V at 150 °C. Low VF reduces conduction loss, while the ultra-short reverse recovery time (15ns, typical) enables switching and minimizes switching loss.
