The DF30SC4M-7102 is a Schottky diode and rectifier manufactured by Shindengen. It is a single diode and rectifier with a VRM (Voltage-Rated Maximum) of 40V and an IFSM (Instantaneous Forward Surge Maximum) of 360A. This part is designed for use in high voltage and high current applications, such as servers, automotive electronics, and industrial power supplies. It features a low forward voltage drop, fast switching times, and low power losses. It is also resistant to surge conditions and is capable of withstanding higher voltages than traditional rectifiers.
