PACDN042
ESD Protection Diode
Low Clamping Voltage
Product Description
The PACDN042/43/44/45/46 family of surge protection 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.
Features
• Two, Three, Four, Five, or Six surge protection
• Compact SMT Package Saves Board Space and Facilitates Layout in
