TPD2E001: Anti Lightning Induction

Guru 10845 points
Part Number: TPD2E001
Other Parts Discussed in Thread: ESDS312, TPD4E1U06

Hello E2E,

Our customer is using the TPD2E001 on USB_Bus for MCU, it's will be damaged by lightning induction.
Clamping voltage of general varistor is high more than VBUS of USB, therefor they can't use on USB_D+/-.
Does TI have the best solution?


  • Hello,

    Our highest protection device is ESDS312 which has 25A surge current and extremely low clamping voltage. However it is 3.3V which is fin for USB D+/- just not for VBUS. Otherwise I would say TPD4E1U06 is our highest protection device for 5V but it is 4 channel.
