Bourns TBUs feature current-disconnection function

Bourns Transient Blocking Units
Mouser Electronics is stocking the Bourns Transient Blocking Units (TBU) circuit-protection devices - winner of EDN's 2008 Innovation in Power Semiconductors award.
The Bourns TBU series provides an effective barrier in nanoseconds by blocking a transient through a current-disconnecting mechanism, rather than diverting or shunting the surge to ground.
The TBUs feature high-speed surge-protection, which protects against short circuits, AC power cross, induction and lightning surges.
All Bourns TBU products are resettable for full functionality after multiple fault events, offer a high bandwidth of three GHz and are designed for telecommunication, industrial and data communications systems.
Bourns has created four diverse TBUs with wide-ranging impulse and RMS voltages, trigger current levels and footprints.
The P40 series was designed for VDSL protection, the P-G series for voice protection, the C series for general electronics protection and the P-U series for Ethernet protection.
