Benefits
Trisil™ technology is not subject to ageing and
provides a fail safe mode in short circuit for a
better protection.
This device can be used to help equipment to
meet main standards such as UL1950,
IEC 950 / CSA C22.2 and UL1459.
Trisils have UL94 V0 approved resin.
SO8 package is JEDEC registered.
Trisils comply with the following standards
GR-1089 Core, ITU-T-K20/K21, VDE0433,
VDE0878, IEC 61000-4-2.
Applications
Dedicated to data line protection, this device
provides a tripolar protection function. It ensures
the same protection capability with the same
breakdown voltage in both common and
differential modes.

Description
The TPN is a low capacitance transient surge
arrestor designed for protection of high debit rate
communication networks. Its low capacitance
avoids distorsion of the signal as it has been
designed for T1/E1 and Ethernet networks.
