APPLICATIONS INFORMATION
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
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 2
Protection of four data lines with bias and power supply
isolation resistor.

The NUP4114HMR6 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.

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.

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.
