PRODUCT OVERVIEW
PulseGuard ESD Suppressors help protect sensitive elec-
tronic equipment against electrostatic discharge (ESD).
They supplement the on-chip protection of integrated cir-
cuitry and are best suited for low-voltage, high-speed
applications where low capacitance is important.
Applications such as computer I/O ports (eg. video dis-
plays), network hardware, cell phone data ports, point-of-
sale terminals, and industrial controls will benefit
from this new technology. PulseGuard suppressors use
polymer composite materials to suppress fast-rising ESD
transients (as specified in IEC 61000-4-2 and MIL-STD-
883E).

DESIGN CONSIDERATION
1,000V, typical
Because of the fast rise-time of the ESD transient, place-
ment of PulseGuard suppressors is a key design consider-
ation. To achieve optimal ESD suppression, the devices
should be placed on the circuit board as close to the
source of the ESD transient as possible. Install

ESD Pulse Withstand1
PulseGuard suppressors directly behind the connector so
that they are the first board-level circuit component
encountered by the ESD transient. They are connected
from signal/data line to ground.

Notes:
1. 8 kV direct discharge method, per IEC 61000-4-2.
2. Measured at 1 MHz.
3. Measured at 6 VDC. Testing at fast ESD pulse rates (1-20Hz) may
cause a change in leakage current performance (6µA, max).
