Electrostatic Discharge (ESD) Protection Design Guide
ESD Electrostatic Discharge (ESD) Protection Design Guide ABOUT THIS GUIDE Choosing the most appropriate suppressor technology requires a balance between equipment protection needs and operating requirements, taking into account the anticipated threat level. In addition to the electrical characteristics of suppression devices, the form factor/package style must also be considered. This guide is designed to summarize some of the comprehensive ESD solutions that Littelfuse offers, and help designers narrow to technologies appropriate to their end application: Table of Contents Page Introduction 2 General Purpose ESD Protection 3-4 Ethernet and Lightning Surge Protection 5 Low Capacitance ESD Protection 6-7 Application Specific Device Selection USB1.1 USB2.0 USB3.0 (Two Device Solution) USB3.0 (Integrated Solution) USB3.1 (Type C Compliance) HDMl HDMI (Includes protection for Ethernet and 5V power) Display Port DVI (Digital Video Interface) Ethernet, Intra-building Lightning Immunity (GR-1089) Non-PoE Ethernet, Inter-building Lightning Immunity (GR-1089) Ethernet, Tertiary Only Lightning Immunity (General) Ethernet (ESD only) 2.5 and 5.0 Gigabit Ethernet xDSL, Intra-building Lightning Immunity (GR-1089) and ESD T1/E1/J1 Carrier eSATA 1394a/b LVDS (Low Voltage Differential Signaling) Audio (Speaker/Microphone) Analog Video Keypad/Push Buttons SIM Socket RS-485 RS-232 CAN Bus LIN Bus Touchscreen 8 8 9 10 11 12 13 1 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 Legal Disclaimers 36 2016 Littelfuse, Inc.

APPLICATION SPECIFIC DEVICE SELECTION USB3.1 (Type C Compliance) Considerations: SuperSpeed lines operate up to 10 Gbps, so lowest unidirectional capacitance is required. Configuration control is logic line, helps determine polarity of the connection, and voltage transfer level. SBUx is used to support DisplayPort communication across the SuperSpeed lines USB 2.0 is a bidirectional interface under Type C protocol, different than historical USB 2.0 Application Schematic: B Row A Row *Packages shown as transparent SSTXp1 SSRXp1 SuperSpeed Lines Unidirectional SuperSpeed Lines Unidirectional SSRXn1 SuperSpeed Lines Unidirectional SuperSpeed Lines Unidirectional SSTXn1 SPHVxx Vsus Power 5V-20V, 2-5 AMP CC1 Config Control PoweredUSB Sideband 2 DisplayPort Enable Dp1 No Pin Dn1 USB2.0 , But Bidirectional SP3022 USB2.0 , But Bidirectional No Pin SBU1 Sideband 1 DisplayPort Enable SP1003 or SP1006 CC2 Config Control PoweredUSB Vsus SSRXn1 Power 5V-20V, 2-5 AMP SPHVxx Vsus SSTXn2 SuperSpeed Lines Unidirectional SuperSpeed Lines Unidirectional SSTXp2 SuperSpeed Lines Unidirectional SuperSpeed Lines Unidirectional SSRXp1 Recommended TVS Diode Arrays: Ordering Number ESD Level (Contact) 1/0 Capacitance @ VR OV #of Channels VRWM Packaging RF3077-000 12kV 0.2pF 4 6V µDFN-10 (2.5x1.Omm) SP1003-01 ETG 30kV 30pF 1 5V SOD882 (0402) SP1006-01 UTG 30kV 25pF 1 6V 0201 DFN SPHVxx-01 ETG 15 to 30kV 25 to 60pF 1 12-36V SOD882 (0402) SP3022-01 ETG 22kV 0.35pF 1 5.3V SOD882 (0402) SP3022-01WTG 22kV 0.35pF 1 5.3V Flipchip 0201 2016 Littelfuse, Inc 12 v.1510 -2

An Electrostatic Discharge (ESD) safe work area and proper ESD handling procedures (that conform to ANSI/ESD S20.20 -1999 or ANSI/ ESD S20.20-2007) are mandatory to avoid ESD damage when handling subassemblies or components found in the MS2717A. Additional information pertaining to ESD can be found at the ESD Association Web site:
IEC 61000-4-2 ESD Ed.2.0 2008 Immunity to the discharge of electrostatic electricity CONDUCTED RF EQUIPMENT POWER AMPLIFIERS Accelonix EMC workshop 17-9-2019. Electrostatic Discharge (ESD) ESD is the most common EMC test performed. ESD is a good starting point. .
1 IEC 61000-4-2 System ESD Immunity 1.1 IEC61000-4-2 Overview The IEC 61000-4-2 standard covers system level ESD immunity. Electrostatic Discharge can be very harmful to a system and even a small amount of voltage can damage components. Most systems require some sort of IEC ESD protection, as any user accessible areas can be subjected to ESD .
ELECTROSTATIC DISCHARGE (ESD): Proper handling of ESD, plays an important role in protecting devices from electro static damages, reduces the losses and increase productivity.
