TBU-DT085-200-WH Description

Short technical summary and product information.

The Bourns TBU-DT085-200-WH is a dual unidirectional high-speed surge protection component from the TBU-DT series. It provides overcurrent and overvoltage protection by blocking surges up to its rated limits, tripping in less than 1 μs when current reaches the maximum value in one direction. The device is designed for Ethernet ports, protection modules, and general electronics requiring robust circuit protection.

 

Key electrical specifications include a maximum peak impulse voltage withstand of 850 V (duration <10 ms at 25 °C), a maximum continuous AC RMS voltage of 425 V, and a minimum trigger current of 200 mA at 25 °C. The device operates over a temperature range of -40 to +125 °C and can be stored from -65 to +150 °C.

 

The TBU-DT085-200-WH is housed in a 4-VDFN exposed pad surface mount package (supplier device package 4-DFN 5x5 mm). It is RoHS3 compliant (unverified), has an MSL rating of 1 (unlimited), and is REACH unaffected (unverified). The datasheet includes a Prop 65 warning for cancer and reproductive harm.
