Other Parts Discussed in Thread: ISO7521, ISO7641FM, ISO7820, ISO7821, ISO7841, ISO7831, ISO7830

Hi all

Would you mind if we ask ISO7520, ISO7521, ISO7641FM?

<Q1>
Are these devices reinforced insulation products?
As our recognition, reinforced insulation is required UL 1577 Isolation Voltage (Single)(Vrms)=5kV over.

Kind regards,

ISO7520/21/41FM have reinforced rating according to some system-level standards but they don't have component-level VDE Reinforced Insulation rating. I suggest to use ISO7821 and ISO7841 which are already released to production and ISO7820 which is planned to be released in June. All these devices are pin-compatible and certified as reinforced.

Saleem san,

And then, what do you plan to release ISO7830 and ISO7831?
Our customer needs 6 forward and 1reverse with reinforced insulation, so we think ISO7830+ISO7841 are better choice.

Kind regards,

Matsumoto-san,

ISO7641FM does not have reinforced insulation at component-level. ISO7841 has reinforced rating at component level by VDE.
