What will be the difference between the IV characteristics of a silicon diode and germanium diode?
The primary difference between silicon and germanium diodes is the voltage needed for the diode to turn on (or become “forward-biased”). Silicon diodes require 0.7 volts to become forward-biased, whereas germanium diodes require only 0.3 volts to become forward-biased.
What is the condition of the Ge diode?
2) According to experimental research, the Ge diode starts to have current at 0.2V in the forward direction, while the Si diode does not start to have current until 0.5V, that is to say, the initial voltages for the two to reach conduction are different.
What is the maximum value of PIV for germanium?
For example, the PIV ratings of silicon diodes are in the neighbourhood of 1000V whereas the PIV ratings of germanium diodes are close to 400V.
What are the differences between Ge and Si diode?
A Silicon Diode is a semiconductor that has both positive and negative charge polarity and can allow an electrical current to flow in one direction whilst restricting another. A Germanium Diode works in the same way but has a low forward voltage which results in it being a low power loss and an efficient diode.
What is a germanium diode used for?
They are, by far, the most common type of diode used in electronics. Germanium diodes are made from germanium. They used to be used a lot in early electronics, such as radios, but they have largely been replaced by silicon diodes….Germanium Diode Circuit.
| Voltage Drops Across Diode at Various Supplied Voltages | ||
|---|---|---|
| 15V | 0.27V | 0.70V |
What is the voltage of germanium diode?
approximately 0.3 volts
Germanium diodes have a forward voltage of approximately 0.3 volts. The maximum reverse-bias voltage that a diode can withstand without “breaking down” is called the Peak Inverse Voltage, or PIV rating.
What is the minimum PIV rating?
Peak Inverse voltage rating is determined by the manufacturer. A typical diode used in rectifiers has a PIV rating of at least 50Vdc at room temperature.
What is PIV rating of diode?
Peak Inverse Voltage (PIV) or Peak Reverse Voltage (PRV) refer to the maximum voltage a diode or other device can withstand in the reverse-biased direction before breakdown. Also may be called Reverse Breakdown Voltage.
Why is Ge preferred over Si?
Ge has higher electron and hole mobility and because of this Ge devices can function up to a higher frequency than Si devices. The germanium diode is also superior to silicon diode in terms of energy loss, current loss, etc. The Ge diode loses only 0.3-0.4 a volt while a silicon diode loses about 0.6-0.7 volts.
What’s the difference between germanium diode and silicon diode?

What is VI characteristics of forward bias?
The VI Characteristics of the PN Junction Diode in Forward Bias. In forward bias condition, the diode gets enough voltage so that it can exceed the value of threshold voltage and provides the carriers with sufficient energy so that it can overcome barrier potential. Hence the forward current is generated in the circuit …
What is the formula of PIV?
PIV = 2Esm – 0.7 The peak inverse voltage of the diode formula which is mentioned above is used because simply one diode can conduct at a time.
