Bourns is pleased to announce the release of the TBU-PL Series to its TBU™ product portfolio. These 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 V ss
, 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 are not 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 lead free solder refl ow profi les.
