Hi, I have am designing a sensor that will be powered at 24V, switched through a relay and up to 4m of cable. When switched through a relay I experience an overvoltage of up to 40v due to the high rise time and cable length. The voltage regulator I am to use has a maximum input voltage of 32v.
Looking at the available TVS's I cannot find a suitable one, one that allows a working voltage of 24v and a clamping voltage of approx. 30v. I also cannot seem to find any suitable over-voltage protection ic.
Does anyone have any advice for protecting the sensor from over-voltage?
Thanks.
