TBU-PK Series - TBU^® High-Speed Protectors
General Information
The TBU-PK 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
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^® device is provided in a surface
mount DFN package and meets industry standard requirements such as RoHS and Pb Free solder
reflow profiles.
