ESD Suppression Design Guide

Electrostatic Discharge (ESD)Suppression Design Guide

Electrostatic Discharge (ESD) is an electrical transient that poses a serious threat to electronic circuits. The most common cause is friction between two dissimilar materials, causing a buildup of electric charges on their surfaces. Typically, one of the surfaces is the human body, and it is not uncommon for this static charge to reach a potential as high as 15,000 volts. At 6,000 static volts, an ESD event will be painful to a person. Lower voltage discharges may go unnoticed, but can still cause catastrophic damage to electronic components and circuits.

about this GuideChoosing 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:

When to Choose PULSE-GUARD ESD Suppressors

The application tolerates very little added capacitance (high speed data lines or RF circuits) ESD is the only transient threat Protection is required on data, signal, and control lines (not power supply lines)

When to Choose TVS Diode Arrays (SPA Diodes)

The device being protected requires the lowest possible clamp voltage, low capacitance (0.30pF 400pF) and low leakage (0.01A 10A)

Board space is at a premium and space-savings multi-line protection is needed Transients other than ESD, such as EFT or lightning, must also be considered

When to Choose Multilayer Varistors (MLVs)

Surge currents or energy beyond ESD is expected in the application (EFT, lightning) Looking to replace high wattage TVS Zener diodes (300W 1500W) Added capacitance is desirable for EMI filtering (3pF 6000pF) Power supply line or low/medium speed data and signal lines are to be protected The operating voltage is above silicon or PULSE-GUARD ESD suppressor ratings

ESD Suppression and Circuit Design Considerations

Proper use of ESD circuit protection helps prevent these failures. Still, selection of a suppression device must recognize that ESD has very short rise and fall timesless than one nanosecond (1ns) in most cases. The International Electrotechnical Commission (IEC) has developed a specification (IEC 61000-4-2) for ESD testing that helps determine if products are susceptible to ESD events.

Littelfuse device engineers use specifications like these to design ESD suppressors with the speed, clamping voltage, and residual current levels that will protect todays sensitive semiconductors and electronic circuitry. Many of these designs have the low internal capacitance needed for high bandwidth communications.

When selecting ESD suppressors, circuit designers need to consider potential coupling paths that would allow ESD to enter their equipment and circuits. These weak points identify areas that should be considered for ESD suppressor installation. Ultimately, designers need to select ESD suppressors with characteristics appropriate for their type of equipment, the component sensitivity, and the environment where it will be used.



esd damage, suppression Requirements and Considerations

ESD Damage

ESD is characterized by fast rise times and high peak voltages and currents up to 30 amps (per IEC 61000-4-2, level 4), which can melt silicon and conductor traces. However, ESD effects can be more subtle. The three types of damage are: 1. Soft Failures Electrical currents due to ESD can change the state of internal logic, causing a system to latch up or behave unpredictably, or cause corruption of a data stream. While this is temporary, it may slow down communications, or require a system reboot in the case of lockup.

2. Latent Defects A component or circuit may be damaged by ESD and its function degraded though the system will continue to work. However, this type of defect often progresses to a premature failure.

3. Catastrophic FailuresOf course, ESD can damage a component to the point where it does not function as intended, or doesnt work at all.

ESD Suppression Requirements

The likelihood of electronic circuit damage is increasing as integrated circuit (IC) dimensions are shrinking to nano-meter sizes. Most ICs operate at low voltages and have structures and conductive paths that cannot survive the high currents and voltages associated with ESD transients.

Another significant trend is the migration to higher fre-quency communication devices to transmit more informa-tion in less time. This means that ESD solutions must not compromise stringent signal integrity requirements at the higher data rates. Therefore, ESD suppressors must have low internal capacitance so that data communication signals are not distorted.

IC designers add a limited amount of ESD suppression to their chips to help avoid damage during manufacturing and assembly processes. However, the level of protec-tion that is added may not be sufficient to protect ICs and other semiconductor devices from ESD during actual usage. Many electronic products, especially portable ones, are used in uncontrolled environments. Portable devices can experience a charge buildup as they are carried by users on their person or in a purse. This energy can then be discharged to another device as the two are connected, usually when a user touches I/O pins on a cable connec-tor. Therefore, end product designers should consider adding ESD suppressors to their circuits.

The chart below shows the relationship between Data The chart below shows the relationship between Data Rates (Protocol), Applications, and Littelfuse ESD suppression products.

The top of the chart shows the standard data protocols, associated data rates, and example end applications that may use the protocols, while the body of the chart shows the applicable Littelfuse ESD suppressors for the various data rates, protocols and applications.

The characteristic of concern here is capacitance. High capacitance suppression devices will tend to add signal distortion as signal frequencies increase; low capacitance devices will maintain signal integrity at high data rates.

Note that an application may use several different data protocols and could use as many different ESD suppressor products. For example, a laptop computer could have RS232, USB 2.0, video, and PS2 mouse ports, as well as others.

The RS232 and mouse ports use relatively slow data rates and could use any Littelfuse suppressor (although higher capacitance multi-layer or silicon parts are preferred for EMI filtering capabilities). The appropriate protector for the video port would depend on the data rate, and since the USB 2.0 port requires an extremely low capacitance suppression device, PULSE-GUARD ESD Suppressor or TVS Diode Array (SPA Diodes) devices should be considered.

If you require further assistance in selecting the appropriate Littelfuse ESD suppressor for your specific circuit, please contact your local Littelfuse products representative.

The information above is intended to help circuit designers determine which Littelfuse ESD suppressors are applicable for given data protocols and data rates. Other key characteristics such as clamping voltage, leakage current, number of lines of protection and ESD capabilities need to be considered, especially where there are overlaps in the recommended Littelfuse ESD suppressor line (ex. IEEE 1284 and Ethernet). This information is detailed on the following pages.

At the upper data rate bounds of the products included above, the capacitances of the suppression device and the circuit board need to be taken into account in order to maintain the signal integrity of the overall system.
