The ESD-SR-S47M is an ESD Suppressors device manufactured by Kemet. It is a bidirectional ESD protection diode array that offers a broad range of ESD protection levels. It can handle 11 kilovolts (kV) of HBM failure, 8 kV contact discharge failure, and 6 kV air gap discharge failure. It is ideal for automotive, industrial, and consumer applications thanks to its 420 VDC maximum working voltage, low leakage current, low capacitance, and rugged construction.
