is a small power device designed for high speed switching and low VF drop. It is constructed with the NPN Schottky barrier rectifier with low forward voltage drop and a low reverse current leakage. It features a high reverse stand-off voltage, surge capability, low junction capacitance, low forward voltage drop, and fast switching speed. It is suitable for various applications such as switching power supplies, PWM control, voltage regulation, battery charging and discharge, and DC-DC power conversion. It is also used in low voltage, low current applications such as inverters, DC-DC regulators, and bridge rectifier circuits.
