PACDN042
Transient Voltage
Suppressors and ESD
Protectors
Product Description
The PACDN042/43/44/45/46 family of transient voltage suppressor
arrays provide a very high level of protection for sensitive electronic
components that may be subjected to electrostatic discharge (ESD).
The PACDN042/43/44/45/46 devices safely dissipate ESD strikes,
exceeding the IEC 61000−4−2 International Standard, Level 4 (±8 kV
contact discharge). All pins are rated to withstand
±20
kV ESD pulses
using the IEC 61000−4−2 contact discharge method. Using the
MIL−STD−883D (Method 3015) specification for Human Body
Model (HBM) ESD, all pins are protected from contact discharges of
greater than
±30
kV.
