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

TVS SMBJ 600W
- DO-214AA, SMBJ (voltage) (Bi-directional) (A 5% tolerance)
Method
- Provent wrong 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.
