TBU-DF Series - TBU® High-Speed Protectors
Reference Application
Basic TBU Operation
The TBU® devices are general use protectors used in a wide
variety of applications, including telecommunications, industrial
communications and automotive battery management systems.
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® TBU® protection devices with a pair
of Bourns® TISP® Overvoltage Protectors or MOVs. For band-
width sensitive applications, a Bourns® GDT may be substituted
for the MOV.
The TBU® device, constructed using MOSFET semiconductor
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 transient events.
When operated, the TBU® device will limit the current to less
than the I
above V
value within the t
duration. If voltage

block
is continuously sustained, the TBU® device will
reset
subsequently reduce the current to a quiescent current level
within a period of time that is dependent upon the applied
voltage.

TBU-DF Series - TBU® High-Speed Protectors
Recommended Pad Layout
TBU® High-Speed Protectors have a 100 % matte-tin termination
unexpected performance issues. For minimum parasitic
finish. For improved thermal dissipation, the recommended layout
uses PCB copper areas which extend beyond the exposed solder
pad. The exposed solder pads should be defined by a solder mask
which matches the pad layout of the TBU® device in size and spac-
ing. It is recommended that they should be the same dimension as
the TBU® pads but if smaller solder pads are used, they should be
centered on the TBU® package terminal pads and not more than
0.10-0.12 mm (0.004-0.005 in.) smaller in overall width or length.
Solder pad areas should not be larger than the TBU® pad sizes
to ensure adequate clearance is maintained. The recommended
stencil thickness is 0.10-0.12 mm (0.004-0.005 in.) with a stencil
opening size 0.025 mm (0.0010 in.) less than the solder pad size.
Extended copper areas beyond the solder pad significantly improve
the junction to ambient thermal resistance, resulting in operation
at lower junction temperatures with a corresponding benefit of reli-
ability. All pads should soldered to the PCB, including pads marked
as NC or NU but no electrical connection should be made to these
pads. Care should be taken to assure no resistive path exists
between the NC or NU pins to any other point to avoid
capacitance, it is recommended that signal, ground or power
signals are not routed beneath any pad. For minimum parasitic
capacitance, it is recommended that signal, ground or power
signals are not routed beneath any pad.

LegalꢀDisclaimerꢀNotice
This legal disclaimer applies to purchasers and users of Bourns® products manufactured by or on behalf of Bourns, Inc. and
its affiliates (collectively, “Bourns”).
Unless otherwise expressly indicated in writing, Bourns® products and data sheets relating thereto are subject to change
without notice. Users should check for and obtain the latest relevant information and verify that such information is current
and complete before placing orders for Bourns® products.
The characteristics and parameters of a Bourns® product set forth in its data sheet are based on laboratory conditions, and
statements regarding the suitability of products for certain types of applications are based on Bourns’ knowledge of typical
requirements in generic applications. The characteristics and parameters of a Bourns® product in a user application may vary
from the data sheet characteristics and parameters due to (i) the combination of the Bourns® product with other components
in the user’s application, or (ii) the environment of the user application itself. The characteristics and parameters of a Bourns®
product also can and do vary in different applications and actual performance may vary over time. Users should always verify
the actual performance of the Bourns® product in their specific devices and applications, and make their own independent
judgments regarding the amount of additional test margin to design into their device or application to compensate for
differences between laboratory and real world conditions.
Unless Bourns has explicitly designated an individual Bourns® product as meeting the requirements of a particular industry
standard (e.g., ISO/TS 16949) or a particular qualification (e.g., UL listed or recognized), Bourns is not responsible for any
failure of an individual Bourns® product to meet the requirements of such industry standard or particular qualification. Users
of Bourns® products are responsible for ensuring compliance with safety-related requirements and standards applicable to
their devices or applications.
Bourns® products are not recommended, authorized or intended for use in nuclear, lifesaving, life-critical or life-sustaining
applications, nor in any other applications where failure or malfunction may result in personal injury, death, or severe property
or environmental damage. Unless expressly and specifically approved in writing by two authorized Bourns representatives
on a case-by-case basis, use of any Bourns® products in such unauthorized applications might not be safe and thus is at
the user’s sole risk. Life-critical applications include devices identified by the U.S. Food and Drug Administration as Class III
devices and generally equivalent classifications outside of the United States.
Bourns expressly identifies those Bourns® standard products that are suitable for use in automotive applications on such
products’ data sheets in the section entitled “Applications.” Unless expressly and specifically approved in writing by two
authorized Bourns representatives on a case-by-case basis, use of any other Bourns® standard products in an automotive
application might not be safe and thus is not recommended, authorized or intended and is at the user’s sole risk. If Bourns
expressly identifies a sub-category of automotive application in the data sheet for its standard products (such as infotainment
or lighting), such identification means that Bourns has reviewed its standard product and has determined that if such Bourns®
standard product is considered for potential use in automotive applications, it should only be used in such sub-category of
automotive applications. Any reference to Bourns® standard product in the data sheet as compliant with the AEC-Q standard
or “automotive grade” does not by itself mean that Bourns has approved such product for use in an automotive application.
Bourns® standard products are not tested to comply with United States Federal Aviation Administration standards generally
or any other generally equivalent governmental organization standard applicable to products designed or manufactured for
use in aircraft or space applications. Bourns expressly identifies Bourns® standard products that are suitable for use in aircraft
