# SS310 (Component)
## Description
DIODE SCHOTTKY 100V SMA(DO-214AC)
The SS310 is a 3.0A Surface-Mount Schottky Barrier Rectifier designed for high-efficiency power conversion and protection applications. It features a low forward voltage drop and fast switching characteristics, making it suitable for DC-DC converters, switching power supplies, freewheeling diodes, polarity protection circuits, and high-frequency rectification applications. The device is commonly available in an SMC/DO-214AB surface-mount package and typically offers a maximum repetitive reverse voltage of 100V.
