ESD224: Comparison: ESD224 vs TPD4E02B04

Part Number: ESD224
Other Parts Discussed in Thread: TPD4E02B04

Hi team

I found both ESD224 and TPD4E02B04 are good for the design, what's the major difference and the design concerns regarding those 2 devices?

Also, I noticed that ESD224 does not have a PCIe support description in the datasheet. As the datasheet describes that ESD224 supports up to 6Gbps of communication I think it would work well with PCIe3.0, could you confirm if this is correct?

Regards

David

    Hi David,

    The main difference is that ESD224 has higher capacitance but better voltage clamping performance due to the internal series resistors (refer to section 8.2 of the datasheet). With that being said, ESD224, will definitely be able to protect a PCIe3.0 interface since that interface only goes up to 1 Gbps per lane. In the datasheet, application lists are not all-inclusive of every interface the device can support. Other interfaces not listed can still be supported depending on the specs of the device.

    Hi Matt

    Thanks! That pretty much concluded my question.

    By the way, is there a certain difference between the ESD and TPD families(such as targeted ee, speed, ESD voltage level...), or is it just the name?

    Regards

    Hi David,

    Glad that I could help! There is no inherent difference between the ESD and TPD families, just the names and the fact that the ESD family is newer.
