UPDATE: ProTek Devices’ Circuit Protection Components for Military and Aerospace Applications

This is an update to a previous video about our circuit protection solutions for military and aerospace applications – it adds more details about relevant industry standards…

According to National Geographic, there are about 100 lightning bolt strikes on the earth’s surface every single second. Each bolt can contain up to one billion volts of electricity. The National Severe Storms Laboratory (NSSL) estimates at least 30 million points on the ground are struck on average each year, just in the USA. In the air, perhaps where the military and commercial air fleets are concerned, it is estimated that each airliner in the USA will be hit by lightning once per year. Furthermore, static electricity, which humans very commonly generate, can have some 35,000 volts of electricity. Either a billion volts or 35,000 volts are far more than enough to destroy important electronics within mission-critical systems. In military and aerospace markets, protecting costly equipment, from vehicles to aircraft and beyond, from such electrical events is a requirement.
Because of these concerns, there are extensive military and aerospace standards defined to protect electronic circuits. MIL-STD-704 defines protection for aircraft, MIL-STD-1275 for vehicles, and MIL-STD-1399 for shipboards. In addition, RTCA/DO-160 defines added circuit protection for aircrafts and MIL-STD-331 adds helicopters. These standards define how to ensure proper circuit protection against lightning, inductive switching, ESD, electromagnetic interference/radio frequency interference (EMI/RFI), and against nuclear electro-magnetic pulses. ProTek Devices offers a wide range of circuit protection components that include TVS arrays and more designed for military and aerospace systems applications.
