Low Capacitance TVS Array



Description

RailClamps are low capacitance TVS arrays designed
to protect high speed data interfaces. This series has
been specifically designed to protect sensitive compo­nents which are connected to data and transmission
lines from overvoltage caused by ESD (electrostatic
discharge), CDE (Cable Discharge Events), and EFT
(electrical fast transients).

The unique design incorporates surge rated, low
capacitance steering diodes and a TVS diode in a
single package. During transient conditions, the
steering diodes direct the transient current to ground.
The internal TVS diode clamps the transient voltage to
a safe level. The low capacitance array configuration
allows the user to protect up to four high-speed data
lines.

The RClamp0504P is in a 6-pin, RoHS compliant,
SLP1616P6 package. It measures 1.6 x 1.6 x

0.60mm. The leads are spaced at a pitch of 0.5mm
and are finished with lead-free NiPdAu. They may be
used to meet the ESD immunity requirements of IEC
61000-4-2, Level 4 (15kV air, 8kV contact discharge).
The combination of small size, low capacitance, and high
ESD surge capability makes them ideal for use in por­table applications such as cellular phones, next genera­tion color LCD displays, USB, and multi media card
interfaces.

Applications Information

Device Connection Options for Protection of Four
High-Speed Data Lines

This device is designed to protect data lines by
clamping them to a fixed reference. When the voltage
on the protected line exceeds the reference voltage
the steering diodes are forward biased, conducting the
transient current away from the sensitive circuitry.
Data lines are connected at pins 1, 3, 4 and 6. The
center pin should be connected directly to a ground
plane. The path length is kept as short as possible to
minimize parasitic inductance. Pin 2 is not connected.
The positive reference is connected at pin 5. The
options for connecting the positive reference are as
follows:

1. To protect data lines and the power line, connect
pin 5 directly to the positive supply rail (V
configuration the data lines are referenced to the
supply voltage. The internal TVS diode prevents
over-voltage on the supply rail.

2. In applications where the supply rail does not exit
the system, the internal TVS may be used as the
reference. In this case, pin 5 is not connected.
The steering diodes will begin to conduct when the
voltage on the protected line exceeds the working
voltage of the TVS (plus one diode drop).
