TPD1E05U06: TVS device comparison

Hi Cameron,

Sorry for the not clear abbreviation. MP means mass production.

Because there are some burn out problem on TPD1E10B06.

So, the customer test the device by connecting to DC directly and hope the ESD device can clamp the voltage at near 5.3V which is Max rating HDMI Receiver IC.

I am not very familiar with ESD protection but as my understanding, should ESD device not use to protect the DC level?

Best Regards,

Ben

Hi Cameron,

The customer uses TPD1E10B06 to protect the HDMI receiver and face some burning out problem when they plugin HDMI cable of DVD player into HDMI connector.

They measure the inrush voltage/current as below figure.

Could you kindly reply these questions below?

1. Can this inrush voltage/current be classified as Surge?

2.Can TPD1E10B06 protect this inrush and protect the HDMI receiver in the back?

Thanks,

Ben

Hi Cameron,

I am sorry for the bad question.

Customer said this behavior and waveform doesn't burn out the receiver IC.

I would like to consult with you about the behavior model of our TPD1E10B06. The test setup is as below block diagram.

As my understanding, CH1's voltage will clamp at clamp voltage when the voltage is higher than breakdown voltage.

In this waveform, we didn't see this behavior. So, customer ask why does this ESD didn't work normally in this situation.

Here is one question about it:

• Is the energy of this momentary voltage too small, causing ESD to be inactive? The below table in datasheet shows the VBR test condition is at 1mA. 

Thanks for your kindly help. Please feel free to let me know, if you need anything else.

Ben,
