I have a customer that has designed in the SN65HVD30-EP for an application that has to comply with RTCA/DO-160, section 22, Lighting Induced Transient Susceptibility. Waveform 5A (40us rise, 80us falling to 50%), harshest ground injection is 750V/2250A, pin injection 750V/750A.
How susceptible is this device to lightning strikes? If there is some inherent susceptibility, what's the best way to protect the device?
Are there alternatives in the portfolio (preferably -55C to 125C op temp) that have integrated protection against lightning strikes?
Thanks.
