ISO1212: DO-160 related question for 600V transient withstand capability

Mark Pearson

Part Number: ISO1212

A question from my customer:

Looking at the ISO1212 as a potential solution. Any idea how this would hold up against lightning pin pulses from DO-160?

Details in the attached PPTX file.

Mark,

It looks like waveforms 4 and 1 at level 3 should be ok. Can you provide more details on waveform 3? I need "t" to be defined so I can see about how long that first pulse at 100% lasts.

Respectfully,

Lucas

Customer response:
"The pulse is ran twice at two different frequencies. 1MHz and 10MHz.
The duration of the damping varies a lot. Assume that at t = 20us that the pulse returns back to 0V"

Mark,

From the data presented I would expect the ISO1212 to be able to handle this. However, we haven't formally tested this device for this situation. Does the customer intend to test the device in their system and would they be able to inform us as to how the ISO1212 performed?

Respectfully,

Lucas

Thanks.
I'll ask about the testing question.
