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

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.
