Diodes

• The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction), while blocking current in the opposite direction (the reverse direction).
• Reference link
• Vrrm = Repetitive peak reverse voltage, Peak Repet. Reverse Voltage
• Ifav = Max. average forward rectified current

Schottky Diode Series

• 1N58XX - https://en.wikipedia.org/wiki/1N58xx_Schottky_diodes
• Average Rectified Forward Current = If
• Peak Repetitive Reverse Voltage = Vrrm
• Reverse voltage = Vr

Usage

• Provent wrong user connection - serial forward connect a viode, will have 0.7V dropout.
• Over voltage protection - reversed connect in power, when voltage over diode voltage, will short connect power. Fuse resistor should also added.
