IEC 61000-4-2 response

The goal of a protection device is to protect against parasitic disturbances. HDMI 1.4

standard specifies a 8 kV contact discharge requirement according to IEC 61000-4-2. The

test must be performed 5 times with 1 second during each shot.

In Figure 9 shows the ESD measurement when applied to HSP061-4NY8. After a first short

spike, the clamping voltage is limited to less than 20 V at 30 ns and less than 10 V at 60 ns

instead of 8 kV.

There is no ageing phenomenon and the protection remains efficient whatever the number

of surges. It is important to keep in mind most of the integrated circuits are ESD rated

between 500 V and 2 kV (human body model) thanks to internal protection.
