☑ Voltage Drop Across Germanium Diode

Forward voltage for a diode varies only slightly for changes in forward current and temperature. In a small silicon diode operating at its rated currents the voltage drop is about 06 to 07 volts.

The value is different for other diode types schottky diodes can be rated as low as 02 v germanium diodes 025 to 03 v and red or blue light emitting diodes leds can have values of 14 v and 40 v respectively.

Voltage drop across germanium diode. This is called forward current. Citation needed. It is necessary that a diode get this voltage so that the diode can conduct.

The value is different for other diode typesschottky diodes can be rated as low as 02 v germanium diodes 025 to 03 v and red or blue light emitting diodes leds can have values of 14 v and 40 v respectively. A diode is a device that drops a specific voltage across its terminals. Germanium diodes need roughly 02v across it in order to conduct current.

The voltage dropped across a conducting forward biased diode is called the forward voltage. The value is different for other diode typesschottky diodes can be rated as low as 02 v germanium diodes 025 to 03 v and red or blue light emitting diodes leds can have values of 14 v and 40 v respectively. Without the threshold voltage being reached the diode cannot conduct current.

However the voltage for the 1n34a diode is measured with a current around 10ma. In a small silicon diode operating at its rated currents the voltage drop is about 06 to 07 volts. Silicon diodes need roughly about 07v across it in order for current to flow.

Germanium diodes a germanium diode such as the 1n34 pictured above will typically have a forward voltage drop of just 03 volts which means they are much more efficient. Germanium diodes have a much lower threshold voltage than silicon diodes. Crystal radio receivers depend on the 1n34a germanium diodes rated forward voltage drop the amount of voltage before is starts to conduct of 3 volts.

Therefore the total forward voltage drop is up to 14 volts a huge amount in low voltage systems and even for 12v battery charging applications. When voltage is applied across a diode in such a way that the diode prohibits current the diode is said to be reverse biased. Silicon diodes are rated around 7 volts.

In a small silicon diode operating at its rated currents the voltage drop is about 06 to 07 volts. A germanium diode has a voltage drop of approximately 03v across its leads.
