The TBU-PL Series are high-speed protectors used in voice/
VoIP SLIC applications.The maximum voltage rating of the TBU
device should never be exceeded. Where necessary, an OVP
device should be employed to limit the maximum voltage. A
cost-effective protection solution combines Bourns
protection devices with a pair of Bourns
sensitive applications, a Bourns
the MOV. If EN55024 EMC compliance is required, the TBU
device may require capacitors to be fi tted between the Tip and
Ring connections and ground.

The TBU
technology, placed in the system circuit will monitor the
current with the MOSFET detection circuit triggering to provide
an effective barrier behind which sensitive electronics are not
exposed to large voltages or currents during surge events. The

current exceeds the TBU

After the surge, the TBU

device will automatically reset on lines which have no DC bias
or have DC bias below V
If the line has a normal DC bias above V

engineers can provide further assistance.
