Protecting sensitive applications from the potentially damaging effects of surges that can cause current and voltage to rise above normal operating levels, the TBU PL-Series responds in 100 nanoseconds. The resettable circuit protection devices also feature significantly lower let-thru energy and overshoot protection, which reduces stress on the SLIC and the printed circuit board (PCB) for increased reliability and product life. The TBU series also cuts the circuit protection component count to three devices compared to the seven needed in a conventional gated thyristor solution because there is no need for peripheral R-C or L-C components nor additional GDTs for increased surge requirements that take up valuable PCB space and increase manufacturing costs.
The Bourns TBU PL-Series is available in three voltages (850, 600, and 500) and two operating current levels (100 and 200 mA) that match worldwide standards and SLIC chipset requirements. Product samples, evaluation boards, and sample kits are available now through Bourns’ distribution partners.
