TRANSIENT BLOCKING UNITS T85 5 007 4 E 0072550 2 Bourns Adds TBU-DT & TBU-KE Series to its TBU(R) Product Portfolio Riverside, California - TO BE RELEASED DECEMBER 23, 2010 - Bourns is pleased to announce the release of its TBU-DT and TBU-KE Series. These products are low capacitance unidirectional high speed protection components, constructed using MOSFET semiconductor technology, and designed to protect against faults caused by short circuits, AC power cross, induction and lightning surges. The TBU-DT Series offers a dual channel option while the TBU-KE Series are single channel devices. Series Description Max. Impulse Voltage Max. RMS Voltage Trigger Current Levels Footprint (mm) TBU-DT065 TBU-DT085 Dual Unidirectional 650 V 850 V 300 V 425 V 100, 200, 300, 500 mA 5.0 x 5.0 TBU-KE025 250 V 100 V TBU-KE040 TBU-KE050 Single Unidirectional 400 V 500 V 200 V 250 V 50,100, 200, 300, 500 mA 5.0 x 2.5 This Bourns(R) TBU(R) high speed protector placed in the system circuit will monitor the current with the MOSFET detection circuit triggering, therefore providing an effective barrier for sensitive electronics against large voltages or currents during surge events. The TBU-DT and TBU-KE Series are available in a surface mount DFN package which meets industry standard requirements such as RoHS* and Pb Free solder reflow profiles.
