High Inrush Current Capability 650V 6A/8A/10A SiC Schottky Barrier Diodes XBSC41/XBSC42/XBSC43 Series

Torex Semiconductor Ltd. has developed the 650V SiC Schottky barrier diode series “XBSC41/XBSC42/XBSC43,” featuring excellent resistance to inrush current and surge current.

The XBSC41/XBSC42/XBSC43 series supports a 650V voltage rating and offers current ratings of 6A, 8A, and 10A, enabling flexible device selection according to application requirements and design conditions. With its low reverse recovery characteristics, the series reduces switching losses and realizes highly efficient power conversion.

In addition, by minimizing the figure of merit (FOM) (Fig. 1), the series significantly reduces power loss and enables high-efficiency operation, while also greatly enhancing IFSM (surge forward current) capability (Fig. 2). This ensures stable operation even in harsh environments where severe surge current or inrush current may occur, contributing to improved overall system reliability.

Achieving both high efficiency and high reliability at a high level, this series leverages the fast-switching performance and low-loss characteristics inherent to SiC devices, while also allowing sufficient design margin during startup and inrush current events. It is well suited for a wide range of reliability-critical applications, including switching power supplies, home appliances, and general-purpose inverters.
