What voltage is required for the germanium diode to work?
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 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 voltage does germanium junction diode start conducting?
0.3 V
The germanium diode conducts at 0.3 V and silicon diode at 0.7 V.
What are typical barrier voltages for a germanium and a silicon diode?
Typically at room temperature the voltage across the depletion layer for silicon is about 0.6 – 0.7 volts and for germanium is about 0.3 – 0.35 volts. This potential barrier will always exist even if the device is not connected to any external power source, as seen in diodes.
What is the forward voltage drop of germanium diode?
0.3 volts
However, germanium diodes have the advantage of an intrinsically low forward voltage drop, typically 0.3 volts; this low forward voltage drop results in a low power loss and more efficient diode, making it superior in many ways to the silicon diode.
What is the maximum value of PIV for germanium?
Germanium Diodes
| Peak Inv. Voltage PIV | Max. Aver. Rectified Current lo At 25oC | |
| Part no. | Volts | MA |
| 1N34A | 60 | 50 |
| 1N60 | 50 | 30 |
What is the voltage drop of a diode?
Answer: A Silicon Diode will have a voltage drop of approximately 0.7V across its leads. A diode is a device that drops a specific voltage across its terminals. It is necessary that a diode get this voltage so that the diode can conduct.
What are its typical values for Ge and Si diodes?
Ge and Si diodes start conducting at 0.3V. and 0.7V. respectively. In the following figure if Ge diode connection are reversed, the value of Vo.
What is a good replacement for 1n60 diodes?
Some places are selling silicon diodes as a substitute or equivalent replacement with the 1N60 number as germanium. Some of there data sheets even say germanium in the header but state silicon in the data area.
Can I use silicon diodes instead of germanium?
Some places are selling silicon diodes as a substitute or equivalent replacement with the 1N60 number as germanium. Some of there data sheets even say germanium in the header but state silicon in the data area. Mine are germanium point contact diodes and not Schottky Silicon Diode.
What is the voltage of a 1N5817 diode?
Both diodes are germanium and both have a forward voltage drop, (often called “turn-on” voltage — where a diode begins conducting), of about 0.3V. A diode with even lower forward voltage is the 1N5817, a Schottky diode, which has a forward voltage of about 0.16 volts.
What is 1n60 used for in circuits?
The 1N60 is also used in sound effect circuits, used as clippers in Guitar pedals. Some places are selling silicon diodes as a substitute or equivalent replacement with the 1N60 number as germanium. Some of there data sheets even say germanium in the header but state silicon in the data area.
