ESD Protection Solutions for High Speed Communication Ports

By Ian Doyle – Marketing Director, ProTek Devices

Introduction

Electrostatic discharge (ESD) occurs when a charge is exchanged between two objects of unequal charge potential. ESD most often occurs between people and metal objects. It is a result of an electron build-up behaving as a capacitor when dielectric isolation is available. Manmade materials, such as shoe soles, achieve dielectric isolation while someone walks on carpet creating kinetic energy. The potential threat of an ESD transient poses a challenge to system designers to incorporate overvoltage protection. Often, the included protection must have capacitance while not degrading the transmission rate. Traditionally, the use of a high capacitor was used to provide protection. However, due to high speed requirements, the capacitance per line must be significantly reduced. It must be done while still providing overvoltage protection against potential threats. Threats can include ESD, electrical fast transients (EFT), or surges. This paper discusses standard requirements for ESD. It highlights overvoltage protection solutions for the most common high speed interfaces. These include USB, HDMI and Ethernet ports, as shown in Table 1.

The IEC 61000-4-2 ESD Standard

The International Electro-technical Commission (IEC) has defined a Human Body Model (HBM) ESD event. The intent is to guide designers in implementing adequate protections in their electrostatic applications. The IEC defined the HBM ESD discharge impulse, with four levels, in standard 61000-4-2. It has a rise time of less than 1ns and decay time of 60ns. This is highlighted in Figure 1.

Fig 1 IEC 61000-4-2 HBM Pulse Graph

As a system requirement, the four levels of IEC 61000-4-2 are shown in Table 2. They are up to ±8 kV contact / ±15 kV air discharges for ESD transients in systems. In some applications, a higher level is specified for enhanced contact and air discharge specifications. This is because human body models can reach ±25 kV in static-rich environments.

To select appropriate overvoltage / ESD protection levels, designers must consider what external transients will be applied to equipment in installation or operational mode. Considerations include ESD, EFT, surge, lightning or mis-wiring. Manufacturers of Integrated Circuits (IC) with electrostatic sensitive devices design a level of protection into the IC. This is to increase robustness during potential board manufacturing overvoltage incidents. However, added protection circuits increases costs in a device by consuming expensive silicon real estate. To minimize such costs, IC manufacturers often design only to the level 1 standard. The IEC 61000-4-2 Level 1 protects against 1-2 kV contact voltage. However, HBM ESD voltages are nature determined – they are real-world and not just for during manufacturing. These real HBM ESD voltages and can be ±15 kV or more, which will damage the IC. So, proper IC protection calls for a Level 1 specification as a secondary protection scheme. Read more.

Automotive electronics advances usher in a greater need for circuit protection

ProTek Devices’ VP Pai contributed an article to ECN. The article was featured Jan. 20, 2014. Start reading the article below…

Every year, the automotive industry introduces more features that leverage advanced electronics. Many of these new electronics features are marketed for occupant safety, entertainment and conveniences. Vehicles are introduced with systems for blind spot warnings, lane departure warnings, accident warnings, parking assistance, and much more. This is in addition to established electronics systems – stereos, navigation, LCD displays, and critical basic control and power systems. It is more important than ever to protect the circuitry of these advanced automotive electronics systems. Providing proper circuit protection helps ensure safety while reducing warranty and service related costs for manufacturers.

The Automotive Electronics Council (AEC-Q101) provides standards for automotive circuit protection. This includes: AEC-Q101-001 (electrostatic discharge [ESD] test – human body model); AEC-Q101-002 (ESD test – machine model); AEC-Q101-003 (wire bond shear test); AEC-Q101-004 (miscellaneous test methods such as unclamped inductive switching, dielectric integrity, and destructive physical analysis); and AEC-Q101-005 (ESD test – capacitive discharge model).

Using these standards, circuit protection component manufacturers can provide solutions to prevent circuits from damage by unexpected electrical fast transients (EFT). There are many critical automotive systems requiring protection. The information / entertainment network system includes high speed optical network information. This system provides traffic and other information, the vehicle communications link, video and audio, etc. The body network includes a low-speed multiplex network for data body messages and switches. This typically covers displays, lighting, power features, HAVC, etc. The chassis network typically consists of a proprietary OEM network for safety-critical systems. This includes steering control, powertrain, chassis control, ABS brakes, etc. Finally, the power network system is made of a power distribution network of 14/42 volts. This covers fusing, junction boxes, the main power, wheelhouse (W/H), etc.

There are various typical electrical transients that occur inside these automotive environments, which vary in frequency of occurrence, duration time, and more. For this reason, circuits within automotive electronic systems require circuit protection components designed specifically for the likely electrical transient event. Transient voltage suppressor (TVS) diodes have long been used and proven effective for automotive circuit protection.
