What is the approximate forward threshold voltage of a silicon junction diode?

  1. 0.1 volt
  2. 0.3 volts
  3. 0.7 voltsRespuesta correcta
  4. 1.0 volts

Explicación

A silicon junction needs about 0.7 volts of forward bias before it conducts appreciably. The 0.3-volt figure belongs to germanium, which has a lower barrier.
