AND8308/D − Interpretation of Datasheet Parameters

for ESD Devices.

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

IEC61000−4−2 was written as a pass/fail spec for larger

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

AND8307/D.

NUP4114 Series, SZNUP4114HMR6T1G

APPLICATIONS INFORMATION

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

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.

Option 1

Protection of four data lines and the power supply using

VCC as reference.

I/O 1

I/O 2

I/O 3

I/O 4

VCC

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.

Option 2

Protection of four data lines with bias and power supply

isolation resistor.

10 k

I/O 1

I/O 2

I/O 3

I/O 4

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.

Option 3

Protection of four data lines using the internal TVS diode

as reference.

I/O 1

I/O 2

I/O 3

I/O 4

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

When using diodes for data line protection, referencing to

a supply rail provides advantages. Biasing the diodes

reduces their capacitance and minimizes signal distortion.

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

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.

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.
