Part Number: TPD6S300A
Other Parts Discussed in Thread: TPD4E05U06

Dear *,

what is the benefit of using TPD6S300A to  TPD4E05U06 ?

Does the TPD6S300A  have the same ESD level protection as TPD4E05U06  and + the short to VBUS protection?

BR,

D.

    Hi D,
    TPD4E05U06 is a TVS surge protection diode which supports IEC-6100-4-5 and ESD protection IEC-6100-4-2, and can help clamp voltages during transient events. The TPD6S300A integrates short-to-VBUS protection on CC/SBU lines, removing the need for TVS diodes on these lines. (TVS diode should still be included on VBUS) TPD6S300A also integrates ESD protection (IEC-6100-4-2) on 6 channels (CC1, CC2, SBU1, SBU2, DP, DM). In event of short to VBUS the TPD6S300A will clamp voltage on CC/SBU line to approx. 8V and turn off its internal FET within approx. 70ns protecting sensitive downstream components.

    Hi Kedar,

    so you are saying: ". The TPD6S300A integrates short-to-VBUS protection on CC/SBU lines, removing the need for TVS diodes on these lines."

    How can the TPD6S300A remove the need of TVS diodes but it does not support IEC-6100-4-5 standard?

    So The TPD6S300A has IEC-6100-4-2 + short tot VBUS
    and
    TPD4E05U06 has IEC-6100-4-5 + IEC-6100-4-2

    Hi David,
    The TPD6S300A provides overvoltage protection by opening its internal FETs to protect CC/SBU lines. In the event of short-to-VBUS event, TPD6S300A will open its internal FET within approx. 70 ns and clamp voltage at approx. 8V. (see figure 33. of datasheet)

    This white paper is great at explaining the advantages of TPDxS300 over discrete implementation, as well as design considerations for protection of Type-C designs.
