Description

This device combines a Transil™ used for low

energy surges and a Trisil™ for high energy

surges. This combination provides a surge /

capacitance trade-off compatible with high debit

rates such as ADSL2+ and VDSL. The

combination on the same die makes it compatible

with SOT23-5L package.
