Hello Expert.
Thank you for your special support every day.
I have some questions about ISO7731-Q1.
I'd appreciate if you could answer following questions.
Q1.
What is the difference of DW and DBQ PKG?
Does both PKG have dual capacitor isolation?
Q2.
I'd like to ask about the contents 6.6 Insulation Specifications of datasheet page 6.
Specifically, it is an item of the highlight below.
Q1. Could you tell me the test contents about time dependent dielectric breakdown (TDDB)?
Q2. I understand that the meaning of 1000 VRMS is continuous operating voltage that can guarantee lifetime of over 40 years. Is it right?
Q3.
Is this ISO77xx-Q1 series used by automotive engine unit?
Best Regars.
