PACDN042/43/44/45/46
Transient Voltage Suppressors / ESD Protectors
Features
•
•
•
Two, three, four, five, or six transient voltage
suppressors
Compact SMT package saves board space and
facilitates layout in space-critical applications
In-system ESD protection to 20kV contact
discharge, per the IEC 61000-4-2 international
standard
Lead-free versions available
Product Description
The family of devices consists of the PACDN042,
PACDN043, PACDN044, PACDN045, and PACDN046.
These devices are transient voltage suppressor arrays
that provide a very high level of protection for sensitive
electronic components which may be subjected to
electrostatic discharge (ESD). The PACDN042/43/44/
45/46 devices are designed and characterized to dissi-
pate safely ESD strikes that exceed IEC 61000-4-2
International Standard Level 4 (8kV contact discharge).
All pins are rated to withstand 20kV 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 30kV.
The PACDN042/43/44/45/46 is available with lead-free
finishing, supporting the current global industry move-
ment to lead free manufacturing.
•
Applications
•
ESD protection of PC ports, including USB ports,
serial ports, parallel ports, IEEE1394 ports,
docking ports, proprietary ports, etc.
Protection of interface ports or IC pins which are
exposed to high ESD levels
