Description
File Number: E315805
TBU® Device
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.
