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 on high speed I/O data lines. The integrated
design of the NUP4304MR6 offers surge rated, low
capacitance steering diodes 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.
NUP4304MR6 Configuration Options
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.
reference is connected at pin 5. 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
inductance.
Option 1
positive supply rail (Vcc), the data lines are referenced to the
supply voltage. Biasing of the steering diodes reduces their
capacitance.
The NUP4304MR6 is a low capacitance diode array
The NUP4304MR6 is able to protect up to four data lines
Data lines are connected at pins 1, 3, 4 and 6. The negative

external TVS diode may be added across V
This will prevent overvoltage conditions on the supply rail

by connecting a series resistor between pin 2 and V
10 kW resistor is recommended for this application. This
will maintain bias on the internal steering diodes, reducing
their capacitance.
