Question

What is the cut in voltage of germanium and silicon diodes?

Answer 1

A silicon diode has a voltage drop of approximately 0.7V, while a germanium diode has a voltage drop of approximately 0.3V. Though germanium diodes are better in the area of forward voltage drop, silicon diodes are cheaper to produce and have higher breakdown voltages and current capabilities.

Answer 2

The cut-in voltage of germanium and silicon diodes are 0.3 and 0.7 volts respectively.

• Diodes are current-conducting devices used in the electronic industry. it conducts current in one direction. their resistance can be low or high in different directions.
• There are many types of diodes such as Zenner diode, light-emitting diode, Schottky diode, Photodiode, PN junction diode, laser diode and avalanche diode.
• Diodes are used in rectifiers, switches, signal modulators and voltage regulators.
• The diodes are DC devices because the current in them flows in one direction only.
