PACDN042/043/
044/045/046
Applications
• ESD protection of PC ports, e.g. USB port.
• Protection of interface ports or IC pins
which are exposed to high levels of ESD.
Transient Voltage Suppressor Arrays
Features
• 2, 3, 4, 5, or 6 transient voltage suppressors in a
single surface-mount package
• Compact SMT packages save board space and
ease layout in space critical applications compared
to discrete solutions
• In-system ESD protection to 20kV contact
dischargeper IEC 61000-4-2 International Standard
Product Description
The PACDN042, PACDN043, PACDN044, PACDN045,
and PACDN046 are transient voltage suppressor arrays
that provide a very high level of protection for sensitive
electronic components that may be subjected to electro-
static discharge (ESD). The devices are designed and
characterized to safely dissipate ESD strikes at levels
well beyond the maximum requirements set forth in the
IEC 61000-4-2 International Standard (Level 4, 8kV
contact discharge). All pins are rated at 20kV ESD 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 pro-
tected for contact discharges to greater than 30kV.
