clearly defined in the spec how to specify a clamping voltage

at the device level. ON Semiconductor has developed a way

to examine the entire voltage waveform across the ESD

protection diode over the time domain of an ESD pulse in the

form of an oscilloscope screenshot, which can be found on

the datasheets for all ESD protection diodes. For more

ESD Voltage Clamping

For sensitive circuit elements it is important to limit the

voltage that an IC will be exposed to during an ESD event

to as low a voltage as possible. The ESD clamping voltage

is the voltage drop across the ESD protection diode during

an ESD event per the IEC61000−4−2 waveform. Since the

APPLICATIONS INFORMATION

Option 2

The new NUP4114HMR6 is a low capacitance TVS diode

array designed to protect sensitive electronics such as

communications systems, computers, and computer

peripherals against damage due to ESD events or transient

overvoltage conditions. Because of its low capacitance, it

can be used in high speed I/O data lines. The integrated

design of the NUP4114HMR6 offers low capacitance

steering diodes and a TVS diode integrated in a single

package (TSOP−6). If a transient condition occurs, the

steering diodes will drive the transient to the positive rail of

the power supply or to ground. The TVS device protects the

power line against overvoltage conditions to avoid damage

to the power supply and any downstream components.

NUP4114HMR6 Configuration Options

The NUP4114HMR6 is able to protect up to four data

lines against transient overvoltage conditions by driving

them to a fixed reference point for clamping purposes. The

steering diodes will be forward biased whenever the voltage

Option 3

Data lines are connected at pins 1, 3, 4 and 6. The negative

reference is connected at pin 2. This pin must be connected

directly to ground by using a ground plane to minimize the

PCB’s ground inductance. It is very important to reduce the

PCB trace lengths as much as possible to minimize parasitic

inductances.

Implementing this topology with discrete devices does have

inductance will provide significant benefits in transient

disadvantages. This configuration is shown below:

immunity.

Even with good board layout, some disadvantages are still

present when discrete diodes are used to suppress ESD

events across datalines and the supply rail. Discrete diodes

with good transient power capability will have larger die and

therefore higher capacitance. This capacitance becomes

problematic as transmission frequencies increase. Reducing

capacitance generally requires reducing die size. These

small die will have higher forward voltage characteristics at

typical ESD transient current levels. This voltage combined

with the smaller die can result in device failure.

The ON Semiconductor NUP4114HMR6 was developed

to overcome the disadvantages encountered when using

discrete diodes for ESD protection. This device integrates a

TVS diode within a network of steering diodes.

Looking at the figure above, it can be seen that when a

positive ESD condition occurs, diode D1 will be forward

biased while diode D2 will be forward biased when a

negative ESD condition occurs. For slower transient

conditions, this system may be approximated as follows:

ESD events can have rise times on the order of some

For negative pulse conditions:

As shown in the formulas, the clamping voltage (V ) not

only depends on the Vf of the steering diodes but also on the

L di^ESD/dt factor. A relatively small trace inductance can

result in hundreds of volts appearing on the supply rail. This

endangers both the power supply and anything attached to

that rail. This highlights the importance of good board

layout. Taking care to minimize the effects of parasitic
