New Brochures for Circuit Protection Devices across Multiple Industries

Protek Devices' military aerospace brochure cover

ProTek Devices has new brochures covering some specific applications in which we provide advanced circuit protection devices for. These applications include communications, industrial, and military / aerospace. The brochures are available for download as a PDF here. However, if you email your full name, title and contact details to/; service -the “at” symbol – protekdevices.com, we may also mail you a full-color printed version of any brochure you request. Here is a summary of what is covered in each brochure.

Communications Brochure
Communication interfaces are vulnerable to a variety of transient voltage threats such as electrostatic discharge (ESD), cable discharge events (CDE) and lightning surge. These threats provide the system designer with the challenge to incorporate overvoltage protection that meets or exceeds circuit protection standards while not degrading the transmission rate. Key parameters, such as working voltage, clamping voltage and capacitance, must be taken into consideration when choosing an overvoltage protection device. ProTek Devices offers low profile, space saving circuit protection devices that provide low working voltage, lower clamping voltages and ultra-low capacitance for high-speed communication applications. Download the full digital brochure here.

Industrial Brochure
Today’s industrial applications are as diverse as ever. They include point of sale (PoS) systems that have card readers, modems and serial ports. They also include residential and commercial energy meters and smart meters; industrial displays; appliances; general control systems; instrumentation; photovoltaic systems; LED lighting and many more. Industrial system failures in the field due to improper circuit protection can be costly exercises in terms of time and money. In addition, system downtime can often result in damage to a company’s image or quality reputation – both that of the user and the system provider. Any of these industrial applications are at risk to external threats that can include electrostatic discharges (ESD), electrical fast transients (EFT), surges, lightning or improper wiring. No matter the industrial application, ProTek Devices provides a comprehensive family of overvoltage and overcurrent protection devices to cover them. They are designed to seamlessly integrate within the various electronics design requirements of today’s modern industrial electronics system. The digital brochure is available here.

Military / Aerospace Brochure
According to National Geographic, there are about 100 lightning bolt strikes on the earth’s surface every single second. Each bolt can contain up to one billion volts of electricity. The National Severe Storms Laboratory (NSSL) estimates at least 30 million points on the ground are struck on average each year, just in the USA. In the air, perhaps where the military and commercial air fleets are concerned, it is estimated that each airliner in the USA will be hit by lightning once per year. Furthermore, static electricity, which humans very commonly generate, can have some 35,000 volts of electricity. Either a billion volts or 35,000 volts are far more than enough to destroy important electronics within mission-critical systems. In military and aerospace markets, protecting costly equipment – from vehicles to aircraft and beyond – from such electrical events is a requirement. ProTek Devices has an extensive family of circuit protection components widely used in military and aerospace applications. The components are also designed to be provided in small packages suitable for even the smallest footprint military and aerospace applications. This digital brochure is available here.

We have also made available an updated digital short form catalog and applications solutions matrix.

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.
