16. Diode Selection

Question.2

A diode is placed next to a USB connector to protect the board from voltage spikes and ESD. The selected diode has the DigiKey part number 497-3144-6-ND.

By checking this part number on the DigiKey website, determine what type of diode it is. Is this the correct type of diode for this purpose?

TVS Diode, No – this diode is only used for rectifying AC voltage
TVS Diode, Yes – this diode is made to protect circuits from sudden voltage spikes
Zener Diode, No – this diode is only used to drop voltage
Zener Diode, Yes – any diode near a connector will work
