The TBU
variety of applications. The maximum voltage rating of the TBU
device should never be exceeded. Where necessary, an OVP
should be employed to limit the maximum voltage. A cost-
effective protection solution combines Bourns
devices with a pair of Bourns
applications, a Bourns
Specifi cations are subject to change without notice.
Customers should verify actual device performance in their specifi c applications.

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
TBU
current exceeds the TBU
When operated, the TBU
than 1 mA typically. When operated, the TBU
block all voltages including the surge up to rated limits.
After the surge, the TBU
across 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
across the TBU
surge. In such cases, special care needs to be taken to ensure
that the TBU
one method used to accomplish this. Bourns application
engineers can provide further assistance.
