High-speed protectors for automotive circuits

30 September 2020 Circuit & System Protection

Bourns announced 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 compliance and lead-free solder reflow profiles.
