“The TBU DT-Series
represents a whole new level of circuit protection for sensitive Ethernet ports,” said Ian Doyle, product line manager of semiconductor products at Bourns, Inc. “Ethernet interfaces today are used almost everywhere and are exposed to ever more serious threats Superior protection without compromising performance is now possible for high speed Ethernet ports thanks to the fast-acting capabilities of these devices.”
The new devices provide an integrated solution that minimizes design and manufacturing costs for design engineers that translates into faster time-to-market. In addition, they enable a lower component count that meets OEM demands for smaller circuit boards in space-constrained designs. Protecting against a wide range of hazardous threats, the Bourns® TBU® DT-Series also helps customers eliminate expensive maintenance, repair and system downtime costs.
The Bourns® TBU® DT-Series features eight models and offers continuous AC voltage ratings up to 425 Vrms and nominal trigger currents ranging from 150 mA to 750 mA. The new device family comes in a surface mount DFN package and is lead free and RoHS* compliant. Product samples are available now through Bourns’ distribution partners. As pricing examples, Bourns® TBU-DT-065 and TBU-DT-085-XXX-WH are priced at $.69 each in 15K quantities.
About Bourns® TBU® Technology
The Bourns® TBU® High Speed Protector is an innovative approach to electronics circuit protection. It is designed to block a transient through a current disconnecting mechanism. Rather than a complex interstage coordination between two shunting components, the TBU® device protects systems from both overvoltage and overcurrent surges. The TBU® device provides protection within nanoseconds, essentially eliminating latency common in the circuit protection design, limiting let-through energy. Bourns® TBU® devices have virtually no capacitance or inductance, and therefore can be used in high speed and high bandwidth applications. The TBU® DT-Series features unidirectional operation which is inherently resettable.
