Protecting sensitive electronics and applications from the potentially damaging effects of surges that can cause current and voltage to rise above normal operating levels, the Bourns TBU-CA Series eliminates the need for large shunt protection devices by stopping the damaging currents from reaching protected circuits in less than one microsecond. The circuit protection devices are low capacitance, single bidirectional high speed devices designed to protect against faults caused by short circuits, AC power cross, induction, and lightning surges within rated limits. The resettable devices also feature significantly lower let-thru energy and overshoot protection, which reduces stress on the printed circuit board for increased reliability and product life.
The series is available in five impulse blocking voltages from 250 to 850 V with minimum trip currents of 50 to 500 mA featuring resistance values as low as 3 ohms. Product samples, evaluation boards, and sample kits are available through Bourns’ distribution partners.
