The ESD5Z2.5T1G is an SOD-523 ESD (electrostatic discharge) protection device manufactured by MSKSEMI. It is designed to protect sensitive electronic components from static electricity discharge. It consists of a special combination of Zener diodes and transistors that are combined to form a compact, low-profile SOD-523 package. The Zener diodes are configured in a series circuit with the transistor in parallel, forming an ESD protection component. This device is RoHS compliant and is suitable for low voltage protection applications.
