RS-485 TVS diodes protection part number

[Darcio Prestes]

Hi all. I'm selecting bidirectional TVS diodes for protecting RS-485
transceiver input lines. Any suggestion of a particular part number?
TIA

Why bidirectional? What are you trying to protect against? How many
transceivers? How much space? Cost target?

Is bidirectional the same as bipolar?

Yes, basically a nose-to-nose zener vs. a single zener.

What are you trying to protect against?

I know nothing about TVS diodes.

Think of them as zeners.

You're already on google. Why not just google TVS diodes?

Good Luck!

You expect a slacker to know that?
