SRV05-4A
RailClamp®
Low Capacitance TVS Diode Array
PROTECTION PRODUCTS - RailClamp®
Features
Description
RailClamp® low capacitance TVS array is designed to
protect high speed data interfaces. This series has
been specifically designed to protect sensitive compo-
nents which are connected to data and transmission
lines from overvoltage caused by electrostatic dis-
charge (ESD), electrical fast transients (EFT), and
lightning.
Protection for high-speed data lines to
IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
IEC 61000-4-4 (EFT) 40A (5/50ns)
IEC 61000-4-5 (Lightning) 12A (8/20μs)
Array of surge rated diodes with internal TVS Diode
Small package saves board space
Protects four I/O lines
The unique design incorporates eight surge rated, low
capacitance steering diodes and a TVS diode in a
single package. During transient conditions, the
steering diodes direct the transient to either the
positive side of the power supply line or to ground. The
internal TVS diode prevents over-voltage on the power
line, protecting any downstream components.
Low capacitance: 3pF typical
Low clamping voltage
Low operating voltage: 5.0V
Solid-state silicon-avalanche technology
Mechanical Characteristics
JEDEC SOT-23 6L package
The SRV05-4A is in a 6-lead SOT-23 package. The
leads are finished with lead-free matte tin. Each
device will protect up to four high-speed lines. They
may be used to meet the ESD immunity requirements
of IEC 61000-4-2. The combination of small size, low
capacitance, and high surge capability makes them
ideal for use in applications such as 10/100 Ethernet,
USB 2.0, and video interfaces.
