![]() In other cases, standard current limiting devices can be used together with voltage clamping devices. To pass Aircraft Lightning Protection Test require sizing up TVS to bulky devices which has a cost impact.įigure 2: Clamping voltages on a TVS for two current values. This drives aircraft lightning protection designs to use almost exclusively TVS-only structures. Figure 1 shows a typical schematic of fast surge protection for fast surges combining voltage clamping and current limiting devices mentioned aboveįigure 1: Typical surge protection schematic.įor specific applications, like aircraft lightning protections, tripping speed, reliability, and failure mode concerns prevent the use of MOV and GDT. Most frequent design approach to Electrical Protection is voltage clamping devices (TVS, MOV, GDT) together with current limiting ones (fuses, resistors, polymeric PTC, inductors). A known justification for Electrical Protection is to prevent transitory event like lightning, EMI, short-circuit, as well as transitory power-up effects, from disturbing and possibly permanently damage impacted electronic systems. ![]()
