I was looking through some schottky diodes and saw in their datasheets, that they have characteristic called voltage change of rate [dv/dt]. Most of those I saw have it exactlly 10000. Now, in datasheets, they also specify their junction capacitances, which differ from diode to diode.
My questions are:
- What is voltage change of rate, what does it mean? And how come, they have it exactlly the same?
- Why is junction capacitance in graphs usually a function of reverse voltage and not forward current or something?
I am actually asking for a way to compare these diodes, to figure out which is faster and which would fit my needs.
