MAX3238-Q1 / 1kV impulse testing for RS-232 port

Guru 29690 points
Other Parts Discussed in Thread: MAX3238-Q1

Hi Team,

My customer considers to use MAX3238-Q1 for his automotive application.
He conducted reliability test for MAX3238-Q1 but I heard he couldn't pass the 1kV impulse testing.
The RS-232 port(DOUT1-5, RIN1-3) was shorted to GND pin(the devices permanently damaged) when the voltage applied.
The test condition is the following.

・applied voltage[Vp]=1kV
・applied number:100
・duration time:1us
・time interval:35Hz
・winding wire:2

Is there any solution for the issue?

Best Regards,
