1 MILITARY-AEROSPACE APPLICATIONS Advanced circuit protection devices for overvoltage and overcurrent transient events Only One Name Means ProTek Tion

2 According to National Geographic*, there are about 00 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 0 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,000 volts of electricity. Either a billion volts or,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. Any computer chip exposed to such electrical transients, without proper electrostatic discharge (ESD) protection, will experience catastrophic destruction. An ESD transient can bore through the layers of a device, severing any trace of an integrated circuit in part or in whole. This can cause intermittent or no operation capabilities for the related system.

MIL- STD-704 defines protection for aircraft, MIL-STD-7 for vehicles, and MIL-STD-99 for shipboards. In addition, DO-0 defines added circuit protection for aircrafts and MIL-STD- 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.

A TVS diode, like other semiconductors, has an inherent capacitance. Capacitance is dependent on junction area, doping concentration and the voltage across the diode terminals. The reverse bias voltage is inversely related to device capacitance, as reverse bias increases the device capacitance decreases. As the doping concentration increases, the voltage rating of the diode decreases and device capacitance increases. On the other hand, devices with higher voltage values have smaller junction capacitance. Larger junction area relates to higher current handling capability. But as the device or junction size increases the device capacitance increases along with it. One of the characteristics of a capacitor is lower impedance to time varying signals. The higher the frequency of a signal, lower the resistance offered to it. So when a TVS diode is used in a high data rate application, the intrinsic device capacitance tends to attenuate the signal. Hence, when the device capacitance is large the attenuation suffered by the high frequency signal is greater. ProTek Devices has an extensive family of circuit protection components widely used in any of these military and aerospace applications. The components deliver primary and/or secondary side protection against ESD, electrical fast transients (EFT), surge, and lightning. They can also provide common-mode, differential-mode, and low capacitance protection. ProTek Devices components are well-known for meeting the strictest of standards requirements, from military standards and IEC, to RoHS and REACH, and more. The components are also designed to be provided in small packages suitable for even the smallest footprint military and aerospace applications.
