Overview
The PESD12VS1UAF is a unidirectional ElectroStatic Discharge (ESD) protection diode manufactured by Nexperia USA Inc. This component is designed to provide transient voltage suppression (TVS) protection for a single signal line, safeguarding against damage from ESD and transient overvoltages. It is packaged in a small SOD323 Surface-Mounted Device (SMD) plastic package, making it suitable for a wide range of applications where space is limited.
