Toshiba Launches New Series of Schottky Barrier Diodes

Feature Compact Packages; Optimized Diode Process for use in Small, Portable Consumer Devices

IRVINE, Calif., Sept. 3, 2014 — (PRNewswire) —   Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced two new series of 0.5 to 1.5A class Schottky Barrier Diodes (SBD): the S30 series (30V type) and S40 series (40V type). With options available in a compact 1.0x0.6 mm package size, the new SBDs are well-suited to smart phones and tablet PCs. They also function as highly efficient circuits for wireless power supplies.

Featuring twelve new devices, Toshiba's expanded lineup of SBDs now includes a high peak reverse voltage type (VRM=40V) and a high average rectifying current type (IO=1.5A). Additionally, the new CUS05S30 boasts low VF characteristics and reduces capacitance between terminals (Ct) by 50 percent or more when compared with current products[1]. All of the new devices achieve low VF characteristics by optimizing the diode process. This lower voltage drop provides higher switching speed and better system efficiency.

Additionally, four other package types are available, ranging from the small SOD-882 (CST2: 1.0x0.6mm) to the standard SOD-323 (USC: 2.50×1.25mm) – making Toshiba's SBDs suitable for a number of different applications with varying mounting size requirements.


  • Low forward voltage: VF=28.0 V (typ.) @IF=0.1A (CTS05S30)
  • High Average rectified current: IO=1.5A (CUS15xx, CCS15xx)
  • High Peak reverse voltage: VRM=40V (CxSxxS40)
  • Supporting high-density packaging by using a compact package: 1.0x0.6 mm CTS05S30, CTS05S40)
