Transient Blocking Unit
Americas:
SUMMARY
Blocking, Not Shunting
In designing circuit protection, conventional
wisdom has held that blocking devices that can
cost-effectively block real world surges do not
exist. As a result, most circuit protection schemes
today rely on multiple shunt devices to protect
against surges. However, the currents that can
occur in such surges can be significant (hundreds
of amps) and they can last a very long time (in
the order of one second to hours). This high
current coupled with significant duration places
a very large stress on circuits protected by all
types of shunt protective devices including GDTs,
MOVs and thyristors.
However, the Transient Blocking Unit (TBU™)
Electronic Current Limiter has proven the
conventional wisdom to be outdated. As a
consequence, it is now possible to effectively
block surges and prevent sensitive load
electronics from experiencing high levels of
energy during surge events.

Conclusion
The TBU device provides blocking protection
for both power cross and lightning. Benefits
of the TBU device include overvoltage and
overcurrent protection in one device, extremely
high speed performance, high blocking voltages
and currents, precise output current and voltage
limiting, very high bandwidth, and a small size.
These advantages result in a protection device
which exceeds Telcordia GR-1089 and ITU
K.20/K.21 requirements, provides automatic
protection coordination, and is GHz data rate
compatible all within a minimum of printed
circuit board area.
The TBU protector provides the circuit protection
design community with a simple, superior
protection device.
