Overview
The ESDA25W is a monolithic suppressor designed by STMicroelectronics to protect components connected to data and transmission lines against Electrostatic Discharge (ESD). This device is part of the ESDA series and is specifically engineered to clamp voltage transients just above the logic level supply for positive transients and to a diode drop below ground for negative transients. It is highly integrated and offers robust protection against ESD, making it suitable for a variety of electronic devices.
