Overview
The ESDA14V2SC6 is a quad Transil™ array designed by STMicroelectronics for Electrostatic Discharge (ESD) protection. This monolithic voltage suppressor is engineered to safeguard components connected to data and transmission lines against ESD. It is part of the ESDAxxSCx family, which offers high integration and suitability for high-density boards. The device clamps voltage just above the logic level supply for positive transients and to a diode drop below ground for negative transients, ensuring robust protection against ESD events.
