SENC712A

SENC712A Rev-2021-1 www.elecsuper.com SuperESD - SENC712A 1. Description The SENC712A protects sensitive semiconductor components from damage or upset due to electrostatic discharge (ESD) and other voltage induced transient events. They feature large crosssectional area junctions for conducting high transient currents, offer desirable electrical characteristics for board level protection, such as fast response time, low operating voltage. It gives designer the flexibility to protect one bi-directional line in applications where arrays are not practical. 2.
