ESD4-DFN
LOW CAPACITANCE TVS ARRAY
DESCRIPTION
The ESD4-DFN is a multi-line, low capacitance , 7pF @ 2.5V bias transient voltage suppressor array. This device is
designed to protect applications such as wireless telecommunication devices, PCMCIA cards and other portable
electronics from the damaging effects of ESD and EFT.
The ESD4-DFN has a working voltage of 5.0V and a minimum breakdown voltage of 6.0V. The ESD4-DFN is ideally
suited to protect 5V DC lines and data I/O ports against ESD and EFT and meets IEC 61000-4-2 (ESD) and IEC 61000-
4-4 (EFT) requirements. At higher operating frequencies or faster edge rates, insertion loss and signal integrity are
a major concern. Packaged in the DFN-4 plastic case, the ESD4-DFN should be placed near the connector to provide
maximum protection.
