What is the approximate forward threshold voltage of a germanium diode?
0.1 volt
0.3 volts✓Richtige Antwort
0.7 volts
1.0 volts
Erklärung
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.
