systems such as cell phones or laptop computers it is not
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
information on how ON Semiconductor creates these
screenshots and how to interpret them please refer to

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 NUP4114 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 NUP4114 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.

NUP4114 Configuration Options
I/O 4
The NUP4114 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 on the
protected line exceeds the reference voltage (Vf or
VCC + Vf). The diodes will force the transient current to
bypass the sensitive circuit.
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.
The NUP4114 can be isolated from the power supply by
connecting a series resistor between pin 5 and VCC. A 10 kW
resistor is recommended for this application. This will
maintain a bias on the internal TVS and steering diodes,
reducing their capacitance.

In applications lacking a positive supply reference or
those cases in which a fully isolated power supply is
required, the internal TVS can be used as the reference. For
these applications, pin 5 is not connected. In this
configuration, the steering diodes will conduct whenever the
voltage on the protected line exceeds the working voltage of
the TVS plus one diode drop (VC = Vf + VTVS).

ESD Protection of Power Supply Lines
For this configuration, connect pin 5 directly to the
positive supply rail (VCC), the data lines are referenced to
the supply voltage. The internal TVS diode prevents
overvoltage on the supply rail. Biasing of the steering diodes
reduces their capacitance.
When using diodes for data line protection, referencing to
a supply rail provides advantages. Biasing the diodes
reduces their capacitance and minimizes signal distortion.

layout. Taking care to minimize the effects of parasitic
inductance will provide significant benefits in transient
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 NUP4114 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.
Implementing this topology with discrete devices does have
disadvantages. This configuration is shown below:

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:
For positive pulse conditions:
Vc = VCC + VfD1
For negative pulse conditions:
Vc = −VfD2
ESD events can have rise times on the order of some
number of nanoseconds. Under these conditions, the effect
of parasitic inductance must be considered. A pictorial
representation of this is shown below.

VC = −Vf − (L diESD/dt)
An approximation of the clamping voltage for these fast
transients would be:
For positive pulse conditions:
Vc = VCC + Vf + (L diESD/dt)
For negative pulse conditions:
Vc = −Vf – (L diESD/dt)
As shown in the formulas, the clamping voltage (Vc) not
only depends on the Vf of the steering diodes but also on the
L diESD/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
The resulting clamping voltage on the protected IC will
be:
Vc = VF + VTVS.
The clamping voltage of the TVS diode depends on the
magnitude of the ESD current. The steering diodes are fast
switching devices with unique forward voltage and low
capacitance characteristics.
