I've read a lot about these devices. I don't fully understand the difference between clamping voltage and breakdown voltage. It seems that breakdown voltage is when avalanche breakdown occurs, which I would want to select to be below whatever voltage damage to my circuit would occur at. However, clamping voltage seems to be described as the same thing, just in a slightly different way.
Is anyone able to clarify the differences between those two parameters? To help understand my application, I am designing a device which is to be powered from a vehicle's DC system and is generally not used while the vehicle is off. However, in playing it safe for a solid design, operating voltage of the circuit under "normal" conditions can be described as anywhere between 9V and 16V DC. Damage would occur to the circuit at or above 20V. Total current draw should be no greater than 500mA, but probably around 300mA.
Thanks as always.
