PESDUC523T5VU

PESDUC523T5VU Low Capacitance ESD Protector Description The PESDUC523T5VU is a TVS array designed to protect I/O or data lines 3 from the damaging effects of ESD. it is low capacitance transient voltage suppressors for high speed data interface that designed to protect sensitive electronics from damage or latch-up due to ESD lightning, and other voltage induced transient events. The SOT-523 is a very small package which allows space saving on high density printed circuit board and also gives the designer the flexibility to provide two I/O lines protection. All pins are rated to withstand 15kV ESD pulses using the IEC61000-4-2 1 air discharge method, which can meet the requirement of level 4.

Novices in the area of ESD protection should take following suggestions to heart:  Do not use stubs, but place the cathode of the TVS diode directly on the signal trace.  Do not make false economies and save copper for the ground connection.  Place via holes to ground as close as possible to the anode of the TVS diode.  Use as many via holes as possible for the ground connection.  Keep the length of via holes in mind! The longer the more inductance they will have.
