Toshiba Electronics Europe expanded its extensive portfolio of diodes with the addition of six low reverse-current SBDs. With a peak reverse voltage of 40V, the new CCS15F40, CUS15F40, CBS10F40, CUS10F40, CTS05F40, and CUS05F40 are suitable for voltage boosting circuits in white LED backlights and for liquid crystal displays in mobile devices like smartphones and tablet PCs.

High-speed, low-loss SBDs are activated by majority carriers, making them suitable for high-speed switching due to their low forward voltage and short reverse recovery time. The reverse current of the CCS15F40, one of the new products, is 25 μA (max), which is an approximately 87% reduction compared to conventional products.

Additionally, the new SBD’s thermal runaway temperature is 35°C higher than seen in conventional devices, contributing to stable circuit operations. The CCS15F40 features fast switching due to a low total capacitance of 130 pF (typ.) @VR=0V. A low reverse current helps to lower power consumption of the devices, making thermal runaways unlikely, even in high-temperature environments.

Toshiba's entire line-up of surface mount diode products is available in many package types and sizes. In addition to the industry standard SOD-323 package, Toshiba has introduced leadless surface mounting packages (CST2C, CST2B) and SOD-882 packages (CST2) to the SBD line-up, ideal for applications where light weight, compact size, and high efficiency are of the utmost importance.

The new SBDs are available now. For more details, samples and pricing information, please contact your local Toshiba Sales Office.
