TBU-DB055-100-WH-Q

TBU-DB055-100-WH-Q is a TBU-DB-Q series TBU® high-speed protector. This product is low capacitance dual bidirectional high-speed protection components, constructed using MOSFET semiconductor technology, and designed to protect against faults caused by short circuits, overvoltage transients and faults in battery cells, up to rated limits. 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 currents during transient events. Application includes RS-485 interfaces, exposed sense and data lines, factory automation, automotive battery management systems, protection modules and dongles, process control equipment, test and measurement equipment.
