TPD2E007: Difference between schematic of TPD2E007 and TPD2E1B06

Part Number: TPD2E007

Hello,

I have a question about the difference between schematic of TPD2E007 and TPD2E1B06.

[Q]
- Schematic of TPD2E007(D/S p6)
 

- Schematic of TPD2E1B06(D/S p1)
 

What are the intentions of the difference between these schematics?
I found out that the range of VIO is different.
How do you use these two devices properly?

Thanks for your cooperation.

Best Regards,

    There is no difference in the schematic, the only change is that the TPD2E007 shows with the pins ground shown as shared, whereas the TPD2E1B06 shows them as separated. Both are used the same to provide IO ESD protection to ground for two channels, with as you mentioned the biggest change being the breakdown voltage. I would recommend the TPD2E007 for higher voltage swings and the TPD2E1B06 for interfaces with lower voltage swings. For more information about where to select specific diodes for different interfaces, please see our selection guide.

    Thanks,

    Hi, Alec-san

    Thanks for your comment.
    I understood the difference between TPD2E007 and TPD2E1B06 is breakdown voltage.
    My understanding is that TPD2E007 can accept high voltage swing because TPD2E007 is back to back diode circuit.
    Is it right?

    Thanks for your cooporation.

    Kaede-

    There's no relationship between the voltage swing and whether the diode is back to back, both of those factors are independent. The voltage swing that can be accepted is a function of the doping of the diode, so we can make diodes that have the working range that we chose. The back to back diode does not and any extra voltage swing room because it will be a forward diode voltage drop, rather than a reverse drop. In this case, it just happens that the TPD2E007 has back to back diodes and a wider voltage swing.

    Thanks,
