Overview
The ESDA25L is a Transient Voltage Suppressor Array (TVS) designed by STMicroelectronics to protect components connected to data and transmission lines against Electrostatic Discharge (ESD) transients. This device is part of the ESDAL series, which is ideal for applications requiring reduced line capacitance and board space savings. The ESDA25L can protect one or two lines against ESD transients and can also be used as a bidirectional suppressor by connecting only pins 1 and 2.
