TPD4E001: Abs. maximum ratings

Hiroshi Sato
Expert 2590 points
Part Number: TPD4E001

Hello,

Our customer using TPD4E001DRLR, sometimes failure occur in the end customers.

This device is passed IEC61000-4-2 and 4-5, so they think the cause for failure seems that a burst(61000-4-4) noise had injected

or some continuous excessive current had injected.

Therefore, they want to know the absolute maximum ratings of continuous current for each diode inside the device.

(in almost all discrete ESD protection diode, that value is shown in the datasheet. so they think TPD device can also show it)

Could you show these values ?

Thanks and best regards,

Hiro

    Hello,

    Most ESD diodes do not show the maximum continuous current rating because these device are not for continuous current. These devices are for  quick transients.

    As far as the EFT goes, this is an older part and was not tested to that standard. Do you know what level was tested of EFT? Also when you say there is a failure is that the TPD4E001 failing or the downstream device.

    If you would like you can email me at c-phillips@ti.com if you could send a schematic or maybe some details you could not share publicly.

    Regards,

    Cameron
