The Bourns TBU-DT085-100-WH is part of the TBU-DT Series of Transient Blocking Units (TBU®), providing high-speed surge protection for sensitive electronics. This component is designed to protect against faults caused by short circuits, AC power cross, induction, and lightning surges.
Key electrical specifications include a peak impulse voltage withstand of 850V and a continuous AC RMS voltage rating of 425V. The device operates within a temperature range of -40°C to +125°C. It features a fast trip time of less than 1 μs when current reaches its maximum value in one direction.
This TBU® device is housed in a compact 4-DFN (5x5) surface mount package, making it suitable for space-constrained designs. It is intended for applications such as Ethernet ports, protection modules, process control equipment, and general electronics. The TBU-DT085-100-WH is designed to block surges effectively, acting as a barrier to protect downstream components from damaging voltage and current spikes. After a surge event, the device automatically resets when the voltage across it falls below a specified level.
It meets industry standard requirements including RoHS 3 compliance and Pb Free solder reflow profiles. The device is also rated for Moisture Sensitivity Level 1 (MSL 1).
