I have a circuit that uses a Schottky diode to provide reverse voltage protection.
However, the diode chosen is on a long lead time and an alternative that is immediately available is required.
I've been looking for an alternative Schottky, but due to a number of factors (e.g. a specific footprint size) I'm struggling to find a suitable device.
I was wondering whether I might be able to use a p-n junction diode, but these will likely add more noise into the system which I want to avoid.
Another idea was to try to use a P-type MOSFET instead. However, I'm not sure if these are noisier than than a Schottky. Does anyone know if there is any work comparing and constrasting the noise between these two devices? Or is there a general rule of thumb that suggests that one is generally considered quieter than the other?
