Hello Team,
I am planning to use TPD1E10B09 as an ESD protection for one of my IO channels.
I've seen another ESD diode ESD2CAN which has a different use case from TPD1E10B09.
In ESD2CAN the cathodes of the clamping diodes are connected together while in TPD1E10B09 the cathodes are connected together.
What difference does that make in the circuit?
What is the difference between them and what are their use cases?
Hi Shibin,
I recommend you look at our ESD fundamentals FAQs, specifically the one on reverse working voltage and polarity.
ESD2CAN24-Q1 is a 2-ch bi-directional diode with a working voltage of 24 V.
TPD1E10B09 is a 1-ch bi-directional diode with a working voltage of 9 V.
They can be used on communication or power lines to clamp ESD/Surge events to protect sensitive circuitry. Any end equipments with exposed connectors can be prone to ESD events so there are many different applications for these devices. The datasheet will have a few of the common applications listed on the front page. See the below common applications for the ESD2CAN24:
Our System Level ESD guide goes into detail on common interfaces that need ESD protection.

Sebastian
