TBU-PL Series - TBU® High-Speed Protectors
General Information
The TBU-PL Series of Bourns® TBU® products are low capacitance dual bidirectional 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.
In addition to overcurrent protection, an added feature is the voltage monitoring on the two lines. If the voltage
on the line drops below Vss then the voltage will trigger the device to switch to the blocking state.
The TBU® high-speed protector placed in the system circuit will monitor the current with the MOSFET detec-
tion 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® device is provided in a surface mount DFN package
and meets industry standard requirements such as RoHS and Pb Free solder reflow profiles.
