ADuM1250 compliance with IEC60001-4-2

HI, 

Is the ADuM1250 compliant with IEC 61000-4-2 ESD protection to ±15 kV air gap discharge?

Thanks,

HM

    Hi HM,

     

    The standalone ADuM1250 could not tolerate 15kV air IEC ESD. External TVS devices should be added to protect the data ports from ESD stresses. Here are two TVS devices you can look at.

    1) CDSOT23-T05C may give +/-8kV contact and +/-15kV air protection. However, the capacitance of this device is about 200pF which can limit the maximum data rate to 100kbps.    

    2) AQ3102-02JTG may give +/-8kV contact and +/-10kV air protection.
