THE FEDERAL AVIATION ADMINISTRATION LIGHTNING PROTECTION MODULES DESIGNED FOR LEADLESS DEVICES

The silicon avalanche diode transient suppressor is widely used to protect low level solid state devices against voltage transients. There has been a problem, however, in providing suitable low loss, low inductive installation mountings especially in retrofit cases. This report describes tow mounting systems developed for the FAA, a barrier strip designated FA9455, for direct current, pulsed or audio lines and coaxial holder designated FA9479 for 50 or 72 ohm video or F.R. lines. Tests were performed using both conventionally constructed suppressors and low capacity units at voltage ratings varying from 6.8 volts to over 50 volts and including bipolar and unipolar devices. Square wave tests on the barrier strip, insertion loss tests on the coaxial module and surge testing of both modules indicated that within test parameters, the devices are limited only by the capabilities of the square suppressor used. i.e. They are device limited.
