RailClamp®
TVS Array for USB OTG Interfaces
PROTECTION PRODUCTS - RailClamp®
Features
Description
RailClamps are surge rated diode arrays 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 ESD (electrostatic
discharge), CDE (Cable Discharge Events), and EFT
(electrical fast transients).
Transient protection for high-speed data lines to
IEC 61000-4-2 (ESD) ±15kV (air), ±8kV (contact)
IEC 61000-4-4 (EFT) 40A (5/50ns)
Array of surge rated diodes with internal TVS Diode
Small package saves board space
Protects three I/O lines & power line
Low capacitance (<3pF) for high-speed interfaces
Low clamping voltage
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 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 operating voltage: 5.0V
Solid-state silicon-avalanche technology
Mechanical Characteristics
EIAJ SC-70 5L package
Molding compound flammability rating: UL 94V-0
Lead Finish: Matte Tin
Pb-Free, Halogen Free, RoHS/WEEE Compliant
Marking : F53
The low capacitance array configuration allows the user
to protect three high-speed data or transmission lines.
The low inductance construction minimizes voltage
overshoot during high current surges. This device is
optimized for ESD protection of USB OTG and SIM
interfaces. They may be used to meet the ESD immu-
nity requirements of IEC 61000-4-2, Level 4 (±15kV
air, ±8kV contact discharge).
