Consider the following schematic:
1) I am accustomed to use Schottky diodes to protect my circuits against reverse polarity. However, in my current scenario, user may apply voltage in reverse polarity to LEDs directly. After some research, I started to suspect that every Schottky diode may not be suitable, because while their reverse voltage may be rated enough the Schottky to survive, but their reverse current may exceed of LEDs'.
Is it correct?
2) How is the reverse voltage distributed on components? Is it equal, or completely random, dependent on LED/Schottky characteristics?
3) Consider the reverse voltage to be 20 Volts, and shunt the Schottky. Will each LED handle the reverse voltage (approximately) equally, and they will stay functional?
