TPD8F003: SD Card ESD Protection?

Part Number: TPD8F003
Other Parts Discussed in Thread: TPD4E101,

For protection SD cards, are TPD8F003 or TPDE001-Q1 still recommended?  TPD8F003 inline resistance seems a bit high compared to the other EMI filters I’ve found that are dedicated to SD cards.  I found that one person had issues with the TPD8F003 in the TI forums, but that seemed conversation seemed to dead-end.  Additionally, the ESD guide documentation doesn’t seem to mention them, but recommends TPD4E101 instead.

    For SD cards, I think any of those options should work. I’d recommend TPD4E101 if only ESD protection is necessary, but if EMI filtering is needed TPD8F003 is also a good option but is a larger package.

    Please let me know if you need any additional support.

    Thanks,
    Alec
