  1. One of the primary advantages of using a Schottky diode over a regular diode is their low forward voltage drop. This allows a Schottky diode to consume less voltage than a standard diode, using only 0.3-0.4V across its junctions.
  2. TVS Diodes are generally used to protect against electrical overstress such as those induced by lightning strikes, inductive load switching, and electro-static discharge (ESD) associated with transmission on data lines and electronic circuits.
  3. Overvoltage occurs when the supply voltage rises above the rated voltage of the equipment or motor. ... Overvoltage can be caused by poor regulation of a power source from a utility company, oversized transformers, uneven or varying circuit loading, wiring errors, and electrical insulation or isolation failures.
  4. What is the difference between varistor and thermistor? A varistor is essentially an open circuit until its breakdown voltage is exceeded which point it begins its resistance drops steeply. A thermistor is more of a temperature sensitive resistor; it's not "normally closed", it's a resistor.
  5. Schottky diode are also used as rectifiers in switched-mode power supplies. The low forward voltage and fast recovery time leads to increased efficiency. They can also be used in power supply "OR"ing circuits in products that have both an internal battery and a mains adapter input, or similar.
  6. Polarity of TVS DIode The -C and -CA diodes are bidirectional, there is no polarity marker. On unidirectional diodes the color band usually denotes the cathode.
