1. Product profile
1.1 General description
Unidirectional double ElectroStatic Discharge (ESD) protection diodes in a common
anode configuration, encapsulated in a SOT23 (TO-236AB) small Surface-Mounted
Device (SMD) plastic package. The devices are designed for ESD and transient
overvoltage protection of up to two signal lines.
