ESD protection for analog A/V lines

6 August 2014 Circuit & System Protection

In addition to HDMI, TVs and DVD/ Blu-Ray players/recorders, set-top boxes and other devices are still most commonly equipped with analog audio and video interfaces.

Since the ICs in these devices are extremely sensitive to ESD, video and audio connectors need ESD protection to prevent damage to these downstream electronics.

The EPCOS CeraDiode range from TDK is well suited to provide ESD protection for consumer and IT equipment, and can be used as 1:1 drop-in replacements for semiconductor diodes. Compared to silicon diodes, CeraDiodes offer higher ESD robustness of up to ±1000 pulses according to IEC 61000-4-2, level 4.

These parts offer bidirectional ESD protection for analog audio and video (A/V) lines in SCART, S-video, Component and Composite formats, owing mainly to their combination of low capacitance values for video lines and broad transmission bandwidth for high-quality audio signals.
