PROTECTION PRODUCTS - RailClamp
Features
Description
RailClamp TVS arrays are ultra low capacitance ESD
ESD protection for high-speed data lines to
protection devices designed to protect high speed data
IEC 61000-4-2 (ESD) 25kV (air), 20kV (contact)
interfaces. This series has been specifically designed to
IEC 61000-4-5 (Lightning) 5A (8/20 s)
protect sensitive components which are connected to
IEC 61000-4-4 (EFT) 40A (5/50ns)
high-speed data and transmission lines from overvolt-
Package design optimized for high speed lines

transients).
Low capacitance: 0.25pF typical (I/O to I/O)
The RClamp 7528T has a typical capacitance of only
Low ESD clamping voltage
0.25pF between I/O pins. This allows it to be used on
Extremely low dynamic resistance: 0.30 Ohms (Typ)
circuits operating in excess of 3GHz without signal

The RClamp7528T is in a 9-pin SLP2611N9T package. Mechanical Characteristics
It measures 2.6 x 1.1mm with a nominal height of
SLP2611N9T 9-pin package (2.6 x 1.1 x 0.40mm)
0.40mm. The innovative flow through package design
Pb-Free, Halogen Free, RoHS/WEEE Compliant
simplifies pcb layout and maximizes signal integrity on
