ISO7731: ISO7731 creepage distances

Part Number: ISO7731
Other Parts Discussed in Thread: ISO6731, ISO7831

The creepage distances of ISO7731 and ISO6731 Only 8mm, it cannot meet customer demand that is 11.5mm creepage distances, so I would like to ask if there is an isolation plan that can achieve the creepage distances of 11.5mm? Thank you~

  • Hi Yachne,

    Thanks for reaching out. Like you have stated, ISO7731 and ISO6731 are only available in packages that support a maximum of 8mm creepage. We have another family of reinforced digital isolators, ISO7831, which supports an additional package (ultra wide body SOIC, DWW) offering 14.5mm of creepage. This should be suitable for customer application.

    Let me know if you have any further questions, thanks.
