Schottky Barrier Diodes Ideal For Smartphone LCDs


Toshiba has added six new low reverse-current Schottky barrier diodes (SBDs) with a peak reverse voltage of 40V making them suitable for voltage boosting circuits in white LED backlights and for liquid crystal displays in mobile devices (including smartphones and tablet PCs).

The reverse current of the CCS15F40 is 25μA (max) and its thermal runaway temperature is 35°C higher than previous products, which contributes to stable circuit operations.

The new devices added are: CCS15F40, CUS15F40, CBS10F40, CUS10F40, CTS05F40, and CUS05F40.

The CCS15F40 features fast switching due to low total capacitance of 130pF (typ.) @VR=0V. A low reverse current contributes to the low power consumption of the device, making thermal runaways unlikely, even in high-temperature environments.


In addition to the industry standard SOD-323 package, the firm offers its surface mounting diodes in leadless surface mounting packages (CST2C2, CST2B3) and SOD-882 packages (CST24), which contribute to making devices slimmer and smaller.

“As mobile devices become more and more sophisticated, the use of voltage boosting circuits of 30V or higher will increase,” noted Talayeh Saderi, senior business development manager for TAEC.

The firm said it plans to add higher peak reverse voltage diodes to its product lineup.

The new SBDs are available now. For more details, view the full Press release.
