The ESD5Z2.5T1G part is an unidirectional transient voltage suppressor (TVS) device, manufactured by ON Semiconductor. This device is designed to protect against Electro-static Discharge (ESD). It has a 5.0V reverse voltage rating, with an ESD capability of up to 5,000W. The IEC ESD protection level is a Class 2 device of 8kV contact discharge, and 15kV air discharge. It has peak power dissipation up to 2.5W, with a breakdown voltage of 5.3V typical and 5.6V maximum. The maximum clamping voltage at Ipp is suggested to be 10.5V. It can withstand peak surge currents up to 25A (8/20µs). The device is available in the SMAF and SMA packages.
