Hi,

Could you tell me why VISO is added by revising the datasheet on this time?

Hi Tadahiko-san,

Thank you for posting to E2E! Viso is used to quantify the rms value of voltage the isolator can handle without breakdown for 60 seconds and is tested to comply with UL, IEC and VDE requirements.

Please let me know if there is more information we can provide.

Respectfully,
Manuel Chavez

Chaves-san,

Thank you for your reply.

VISO was not certified previous revising the datasheet.

Why VISO was added? Is it caused by revising VDE?

Best Regards,

Kuramochi

Hi Tadahiko-san,

No problem. This was not added by a change from VDE; it was missing in earlier revisions and now we have added it.

Thank you,
Manuel Chavez
