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.

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.

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").
