The ESD5V0B3-523 is an ESD (electrostatic discharge) Protection Device ROHS manufactured by TECH PUBLIC. It comes in the SOD-523 package, which is an ultra small surface mount diode designed for high-frequency and space-saving applications. This diode functions to protect circuits against transients, providing an effective ESD protection up to 25kV contact discharge levels. It is constructed with a silicon epitaxial planar diode, featuring a reverse stand-off voltage of 5V and a corresponding fast reacting to electrostatic discharge. The device also has low leakage current and a low capacitance value between cathode and anode. The ESD5V0B3-523 is suitable for use in automotive and consumer electronics applications, as well as other protection applications.
