Model TBU-CA-Q Series

Bourns Adds New AEC-Q101 Compliant TBU® High-Speed

Bourns is pleased to announce the release of the AEC-Q101 compliant Model TBU-CA-Q High-Speed Protector series. These products are low capacitance single 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.

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 up to rated limits. The TBU® device is provided in a surface mount DFN package and meets industry-standard requirements such as RoHS compliant and Pb Free solder reflow profiles.
