PulseGuard^®Suppressors

Surface Mount Polymeric ESD Suppressors

RoHS Pb

PGB1 Series Lead-Free 0805 ESD Suppressor

Product Overview

PulseGuard ESD Suppressors help protect sensitive electronic

equipment against electrostatic discharge (ESD). They supplement the

on-chip protection of integrated circuitry and are best suited for low-

voltage, high-speed applications where low capacitance is important.

Data ports utilizing such high-speed protocols as USB 2.0, IEEE1394,

HDMI and DVI can 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),

while adding virtually no capacitance to the circuit.

NOTE: When wave soldering, the gap between pads should be

covered with photo-imageable solder mask to prevent bridging

between terminations under the component. Also the spacing

between the ground contacts should be increased from

.635mm (.025") to .889 (.035").

Design Consideration

Because of the fast rise-time of the ESD transient, placement of

PulseGuard suppressors is a key design consideration. 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

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.
