This range of schottky barrier diodes have much lower reverse voltage and also have extremely low forward voltage for applications that implement the diode in the forward bias direction. Since forward voltage and reverse current are trade-off characteristics, schottky barrier diodes generally come in two options, low forward voltage or low reverse current.  Both types can be found in the Toshiba lineup. Toshiba also offers schottky barrier diodes which allow much higher current, suitable for charging and rectifying purposes.
