What is the voltage for silicon and germanium?
0.7 volts
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 cut in voltage for silicon and germanium semiconductor?
about 0.3V
For different materials of the diode, the threshold voltage is different. For silicon the threshold voltage is about 0.7V and for germanium it is about 0.3V.
What is the voltage drop of a silicon diode vs germanium?
1.2 Differences between Ge and Si Transistor The main difference is that the junction voltage drop is different, the forward voltage drop of the germanium tube is lower about 0.3V, and the silicon tube is higher about 0.7V.
What is breakdown voltage for silicon?
Reverse break down voltage for silicon diode is 6V for a particular doping concentration and forward break down voltage is 0.3V then find approximate current through battery in the given circuit 1092 1092 (1) 2 Amp (2) 1.3 Amp (3) 1 Amp (4) T Amp.
Why is the cut in voltage of silicon and germanium difference?
Silicon is cheaper than Germanium. Therefore, it’s preferred over Ge diode. 12. The forward voltage drop for Germanium junction is less, whereas for Silicon diode the forward voltage drop is low.
Why is the cut-in voltage of silicon more than germanium?
At room temperature, Silicon crystal has fewer free electrons than Germanium crystal. This implies that silicon will have much smaller Collector cut off current than Germanium. Peak Inverse Voltage ratings of Silicon diodes are greater than Germanium diodes. Si is less expensive due to the greater abundance of element.
Why is the cut-in voltage of silicon and germanium difference?
What is the chemical symbol of Germanium?
Ge
Germanium/Symbol
Is Germanium a diode?
may be used as a rectifier because it offers a relatively high resistance for forward bias and very low resistance for reverse bias.
What is the breakdown voltage of LED?
LED Characteristic Curve The reverse breakdown voltage is quite low (5 volts approx). It’s easy to destroy LEDs.
What should voltage be across germanium and silicon diodes?
Assuming ideal components, you will never have 12V across the diodes in the conducting direction. You will have, at most, 0.3V across the Germanium and, at most, 0.7V across the Silicon. So when the Ge and Si diodes are in parallel and in the same direction as the circuit flow, the voltage across the (ideal) diodes will never exceed 0.3V.
Which is correct 0.4V or 0.3V?
Best answer The correct option (3) 0.4 V Explanation: Initiall current will flow through Ge diode drop will be 0.3v. In the second case, Si diode wll conduct and drop across the combination is 0.7v. so, change in Voltage =0.4V Please log inor registerto add a comment.
How does germanium and silicon conduct in a circuit?
As the voltage across the diodes rise, the Germanium will start to conduct first – essentially shorting out the Silicon. So in the circuit shown, only the Germanium is conducting significant current. With the Germanium reversed, it will not conduct at all. So the Silicon will conduct with a 0.7v voltage drop.
