What is the approximate forward threshold voltage of a germanium diode?

  1. 0.1 volt
  2. 0.3 voltsپاسخ درست
  3. 0.7 volts
  4. 1.0 volts

توضیح

Germanium has a lower junction barrier than silicon, so a germanium diode starts conducting at roughly 0.3 volts of forward bias. The 0.7-volt figure is the silicon value.
