SB340 Schottky Barrier Rectifier

The SB340 is a 3.0-Ampere Schottky barrier rectifier designed for low-voltage, high-frequency applications where efficiency is paramount. Utilizing a metal-to-silicon junction with a guard ring for transient protection, it offers significantly lower power loss and higher efficiency compared to standard P-N junction diodes. Its primary advantages are an extremely low forward voltage drop and fast switching speeds, which minimize heat generation and energy loss during operation. This diode is a common choice for freewheeling, polarity protection, and use in low-voltage high-frequency inverters and DC/DC converters. The robust DO-201AD axial package is constructed with a UL 94V-0 flammability-rated molding compound and features a color band to denote the cathode end. Because of its Schottky technology, it is specifically suited for power management systems that require precise control and rapid response times.
