RClamp7528T
Ultra Low Capacitance TVS Array
PRELIMINARY
PROTECTION PRODUCTS - RailClamp®
Features
Description
RailClamp® TVS arrays are ultra low capacitance ESD
protection devices designed to protect high speed data
interfaces. This series has been specifically designed to
protect sensitive components which are connected to
high-speed data and transmission lines from overvolt-
age caused by ESD (electrostatic discharge), CDE
(Cable Discharge Events), and EFT (electrical fast
transients).
ESD protection for high-speed data lines to
IEC 61000-4-2 (ESD) ±25kV (air), ±20kV (contact)
IEC 61000-4-5 (Lightning) 5A (8/20s)
IEC 61000-4-4 (EFT) 40A (5/50ns)
Package design optimized for high speed lines
Flow-Through design
Protects eight high-speed lines
Low capacitance: 0.25pF typical (I/O to I/O)
Low ESD clamping voltage
The RClamp®7528T has a typical capacitance of only
0.25pF between I/O pins. This allows it to be used on
circuits operating in excess of 3GHz without signal
attenuation.
Extremely low dynamic resistance: 0.30 Ohms (Typ)
Solid-state silicon-avalanche technology
The RClamp7528T is in a 9-pin SLP2611N9T package.
It measures 2.6 x 1.1mm with a nominal height of
0.40mm. The innovative flow through package design
simplifies pcb layout and maximizes signal integrity on
high-speed lines. Each device will protect eight lines and
requires less board space than existing solutions.
