I. Device Description
A. General
The SM05 of TVS diode array is designed to protect sensitive electronics from damage or
latch-up due to ESD, for use in applications where board space is at a premium. The
dual-junction common-anode design allows the user to protect one bidirectional data line or
two unidirectional lines.
The SM05 may be used to meet the immunity requirements of IEC 61000-4-2, level 4.
