The Bourns TBU-DT085-500-WH is part of the TBU-DT series of high-speed transient blocking units. It provides overcurrent and overvoltage protection by blocking surges up to its rated limits in less than 1 microsecond. This dual unidirectional device trips when the current reaches 500mA in the forward direction, automatically resetting when the voltage falls to the Vreset level.
Key specifications include a peak impulse voltage withstand of 850V, continuous AC RMS voltage of 425V, and a trigger current of 500mA. It operates over a temperature range of -40°C to +125°C and is RoHS compliant.
Typical applications include Ethernet port protection, protection modules and dongles, process control equipment, and test and measurement equipment. The device is housed in a 4-VDFN exposed pad surface mount package (4-DFN 5x5mm), suitable for compact PCB designs.
