Why is silicon preferred over germanium in diode?
The structure of Germanium crystals will be destroyed at higher temperature. However, Silicon crystals are not easily damaged by excess heat. Peak Inverse Voltage ratings of Silicon diodes are greater than Germanium diodes. Si is less expensive due to the greater abundance of element.
What is the voltage for silicon and germanium?
about 0.3V
Why silicon is preferred over germanium for making electronic devices?
Why is silicon usually preferred to germanium in the manufacture of semiconductor devices? Silicon is abundant on the earth’s surface and therefore cheaper than germanium. The PIV (Peak Inverse Voltage) rating of silicon is much higher than germanium and therefore can withstand much higher temperatures than germanium.
What is the voltage of silicon diode?
Silicon diode – Silicon is the most common material used to make diodes. Silicon has a typical forward voltage of 0.6 − 0.7 V 0.6-0.7\,\text V 0.
How is Zener diode formed?
The Zener diode is made up of heavily doped semiconductor material. The heavily doped means the high-level impurities is added to the material for making it more conductive. The depletion region of the Zener diode is very thin because of the impurities.
What is the difference between diode and zener diode?
A diode is a semiconductor device which conducts in one direction only. A Zener diode is a semiconductor device which conducts in forward biased as well as reversed biased….Comparison Chart.
Parameters | Diode | Zener Diode |
---|---|---|
Application | Diode is used in rectifiers, clippers, clampers etc. | Zener diode is mostly used in voltage regulator. |
How do you spell Zener?
noun. A form of semiconductor diode in which at a critical reverse voltage a large reverse current can flow. ‘When a MOS channel is formed by forward biasing the gate, a Zener tunnel current evolves with a steep turn-on characteristic. ‘
