TRIPOLAR OVERVOLTAGE PROTEC-
TION FOR NETWORK INTERFACES
FEATURES
TRIPLE CROWBAR PROTECTION
PEAK PULSE CURRENT : IPP = 30 A, 10/1000µs
VERY LOW CAPACITANCE :
C = 30 pF
PROTECTS HIGH-SPEED LINE DRIVERS /
RECEIVERS
DESCRIPTION
Dedicated to dataline protection, this device
provides a triple protection function. It ensures
the same protection capability with the same
breakdown voltage both in common mode and
in differential mode.
With a stand-off voltage of 28V and a very low ca-
pacitance, this device is able to protect high-speed
interfaces such as T1/E1 interface.
