Question about ESD suppressor for audio signal.

Hello Inho,

Unfortunately, we do not have any devices with an 18 V Vrwm who's primary function is ESD suppression. However, you could protect the 18 V power line to the amp from surge using a TVS1801, if you don't have a surge protection device already in place.

Matt Smith

Dear Matt,

I attach schematics. 

I'm going to ESD suppressors for power of +18Vdc, +5Vdc, +3.3Vdc like below schematics.

Please, inform me suitable ESD suppressors for that.

Thank you.

Best Regards,

Inho Jeon

Hi Inho,

Please see my recommendations below:

• 18 Vdc power line: TVS1800
• 5 Vdc power line: TVS0500
• 3.3 Vdc power line: TPD1E1B04

Let me know if you have any more questions.

Regards,

Matt Smith

Dear Matt,

Do you have parts TVS0500 and TVS1800 in the same package as TPD1E1B04?

Thank you.

Hi Inho,

Unfortunately we do not. However, the DRV package that the TVS0500 and TVS1800 is much smaller compared to the SMB package many other surge protection devices come in.
