The TBU-CX Series of Bourns
products are low capacitance dual bidirec-
tional high-speed protection components,
constructed using MOSFET semiconductor
technology, and designed to protect against
faults caused by short circuits, AC power cross,
induction and lightning surges.
The TBU
with the MOSFET detection circuit triggering to provide an effective barrier behind
which sensitive electronics will not be exposed to large voltages or currents during
surge events. The TBU
meets industry standard requirements such as RoHS and Pb Free solder refl ow profi les.
*RoHS Directive 2002/95/EC Jan 27, 2003 including Annex.
Specifi cations are subject to change without notice.
Customers should verify actual device performance in their specifi c applications.
