RTCA DO-160, Environmental Conditions and Test Procedures for Airborne Equipment, is a widely used criterion for verifying the capability of equipment to withstand the effects of lightning induced electrical transients.
In Section 22 of this standard, entitled Lightning Induced Transient Susceptibility, the test methods and procedures for performing pin injection and cable bundle testing on aircraft equipment are defined. In order to verify the capability of an electronic system to withstand the effect of lightning induced transients, test procedures define the lightning induced transient by two characteristics.
In the table below for waveforms 3, 4, and 5A, we show the recommended diode clamping voltage (Vc) and power rating (Ppp) at each test level for these waveforms.
