Bidirectional, Dual Channel High-Speed Protectors

Bourns has announced the release of the Model TBU-DF055-100-WH, TBU-DF055-200-WH, TBU-DF085-100-WH and TBU-DF085-200-WH bidirectional, dual channel, High-Speed Protectors (HSPs) for use in data line protection.

The Bourns® Model TBU-DF Series precise and fast switching TBU® protectors are constructed using MOSFET. These TBU® HSPs are designed to protect against faults caused by short circuits, overvoltage transients and faults in battery cells, up to rated limits.

Targeted applications include RS-485 interfaces, exposed sense and data lines, factory automation, protection modules and dongles, process control equipment, test and measurement equipment, and general electronics.

The TBU® High-Speed Protector, placed in the system circuit, will monitor the current with the MOSFET detection circuit, triggering precisely and quickly within 1µs to provide an effective barrier behind which sensitive electronics will not be exposed to large currents during transient events.

Summary of Features:

  • Superior circuit protection
  • Overcurrent protection
  • Blocks surges up to rated voltage limit
  • High-speed performance
  • Small SMT package
  • RoHS compliant
