Toshiba CUHSx Schottky Barrier Diodes

Toshiba CUHSx Schottky Barrier Diodes (SBDs) are suitable for rectifying power supply circuits and protecting reverse currents. These diodes are high-speed switching devices that incorporate Si technology and use a US2H package to achieve low-thermal resistance. These SBDs offer a reverse leakage greater than other types of diodes making them more susceptible to thermal runaway under high-temperature and high-voltage conditions. To improve the efficiency of power supply use, these SBDs are required to have low forward voltage and low reverse current. The DC-DC boost converter ICs are used in voltage-boosting circuits for driving LCD backlight LEDs in portable devices like smartphones, tablets, and notebook PCs. In addition to the DC-DC converter circuits, Toshiba CUHSx Schottky Barrier Diodes are also used in applications such as motor driver circuits, MOSFET gate driver circuits, and freewheeling diodes.
