TPD4E05U06: TI solution recommend

Part Number: TPD4E05U06
Other Parts Discussed in Thread: TPD6E05U06,

Dear Team,

We will have a plan convert to own brand for sales, but new product request has enhance IO spec and add lots of safety certificate (e.g ESD protection should pass 8KV/ 15KV IEC61000-4-5 rule etc).


For example Ethernet switches IO port as below snapshot shown, we necessary support [8* 1GE RJ45 port] * 3-groups = 24*1GE RJ45 ports and necessary add relevant ESD protection devices to prevent for pass safety certificate request.

Does TI has any ESD protection to recommended for support multi-channel signals to implement? (based on use minimum device to achieve)


Based on my use TI.esd device experience before, I only use TPD4E05U06DQAR (for support 4-CH signals) as Fig1 design picture, but it will cause use too much esd device for prevent esd safety….

  • 1-port RJ45 has 8-signals, then it necessary use two TPD4E05U06DQAR


If support 1-group (8 RJ45 port), then it will use sixteen esd protection…. Therefore hopeful TI can give me the recommended esd protection suggestion and try best to reduce the esd device at the same time, tks!!

Many Thanks,
