Bourns® TBU-DB-Q series two channel high-speed protector

Bourns is pleased to announce the release of the Model TBU-DB-Q bidirectional, dual channel, AEC-Q101 compliant high-speed protector for use in automotive applications.

The Model TBU-DB-Q Series of Bourns® TBU® products is precise and fast switching protectors constructed using MOSFET semiconductor technology and designed to protect against faults caused by short circuits, overvoltage transients.

When placed in the system circuit, the TBU® High-Speed Protector monitors the current with its MOSFET detection circuit, triggering precisely and quickly within 1s. This provides an effective barrier behind which sensitive electronics are protected from large currents during transient events, in accordance with its published specifications.
