浪涌抑制器 Dual Unidirectional TBU Device

TBU-DT Series - TBU® High-Speed Protectors

General Information TBU-DT085-500-WH

The TBU-DT Series of Bourns® TBU® (Transient Blocking Unit) products are very low capacitance dual unidirectional high-speed surge protection components designed to protect against faults caused by short circuits, AC power cross, induction and lightning surges.

The TBU-DT series is a unidirectional TBU® device; the TBU® protector will trip in less than 1 μs when the current reaches the maximum value in one direction only, that is when Pin 1 is positive in voltage with respect to Pin 2, and Pin 4 is positive with respect to Pin 3. No current limiting exists in the opposite polarity, and the TBU® device appears as resistive in nature. The reverse current should not exceed the maximum trigger current level of the TBU® device. An external diode may be used to prevent reverse current in DC biased applications.
