PGB Series SOT23 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

and InfiniBand

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).

Features

• Ultra-low capacitance

• Low leakage current

• Fast response time

• 2-lines of protection

• Bi-directional

• Withstands multiple ESD strikes

• Standard JEDEC SOT23 outline

• Compatible with pick-and-place processes

• Available in 3,000 piece reels

Typical Applications

• Servers

• Laptop/Desktop Computers

• Network Hardware

• Computer Peripherals

• Digital Cameras

• External Storage

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.
