Hello,

Can anyone tell me what should be the power rating for the liming resistor used between the TVS diode and high voltage input?

Thanks and regards,

Ibtesam.

Hello Ibtesam,

Welcome to our forum and thank you for your post!

Typically we see customers use something like a 1k, 1W resistor at the electrode inputs to the circuit. You will have to verify that this combination of resistance and power rating is sufficient to handle the expected high-voltage inputs and the clamping voltage used by your TVS diodes.
