TPD4S009 Leakage current

Takumi Suzuki1

Other Parts Discussed in Thread: TPD4E001

Hi,

I would like to ask you a question about the leakage currnt, datasheet page7 Fig2, as below.

I think that the unit of "Vertical axis" seems to be "nA" not "pA".

Is this correct?

And about "Transverse axis", I do not understand well the position of "55".

Could you show me the correct data?

And the leakage current is typically 10nA and max value is 100nA.

The difference (10nA - 100nA) is very large. The major factor of this difference is "temperature", right?

How should we do to keep the current under 10nA?

Thank you for your support.

Best Regards,

    Hi Takumi,

    These devices are low leakage and the graph's vertical axis is correct and approaching 10 nA at 85C, as is specified for a typical unit. The difference between a typical leakage and maximum leakage specification is going to be some differences between different fabrication lots may leak up to 100nA across temp.

    If you are looking for an ultra low leakage of less than 10 nA max, I recommend TPD4E001 due to it's similarity by electrical specifications and packages. The maximum leakage current for TPD4E001 is 1 nA.

    Please let me know how I may further assist you.

    Hi Guy-san,

    Thank you for your reply.

    I understood well about the leakage.

    I will recommend TPD4E001 to my customers in case of needing ultra low leakage.

    Thanks!
