TS3USB221A-Q1: Test condition

Roy Chou1

Genius 12635 points

Part Number: TS3USB221A-Q1

Hi all,

My customer is using TS3USB221A-Q1 for their ESD protection. As I know, spec shows "ESD Performance I/O to GND Per JESD 22 – 12-kV Human-Body Mode" Contact discharge could meet the requirement, but I'm not sure other condition could pass the measurement or not. Could you help us to check the below condition and provide us some basic ESD tech information or file. Thanks.

I also have some question about choosing ESD and replacing competitor rule.

What is the necessary checking rule? I often saw the below spec.

IEC61000-4-2 Level 4

IEC61000-4-4 EFT Protection 80A(5/50ns)

IEC61000-4-5 Surge Protection 6A(8/20us)

When we would like to replace the competitor device, we check the above three spec?

Do we have technical document to choose ESD device or roadmap?
