Germanium was used in early transistors.

Diode en germanium. The type of germanium diode we will use is a 1n34 germanium diode. Older germanium diodes had a larger leakage of current at a reverse voltage but now american microsemiconductor and others supply a range of improved low current leakage germanium diodes. Germanium diodes are not very common these days and are hard to find but are still used in hobby am radio receivers as detectors and also in battery circuits connected to solar panels.

The germanium diode works well for small jobs but most technology needs something that can handle more power. Citation needed at higher currents the forward voltage drop of the diode increases. And the diode can handle a forward current of 150ma and a peak surge current of 500ma.

Germanium compounds are also used for polymerization catalysts and have most recently found use in the production of nanowires. While both perform the same function they only let current pass through them in one direction there are some differences between the silicon and germanium variants. 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.

The 1n34a germanium diode the diode most used in crystal radio sets xtal radio sets. Presently the major end uses are fibre optic systems infrared optics solar cell applications and light emitting diodes leds. This diode can handle a reverse dc voltage of 20v.

One of the most well known germanium diodes is the 1n34 diode. This diode is still used today in some analog technologies and in radio receivers. Historically the first decade of semiconductor electronics was based entirely on germanium.

Widely used for detecting the rectifying efficiency or for switching on a radio tv or stereo etc. A germanium diode is a diode made using the element germanium in stead of silicon silicium. Check the spec sheet to ensure you understand what youre buying.

1n34a diodes are made of a material called germanium a material used for transistors and diodes as one of the first semiconductor materials used commercially. 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. The most obvious is the forward bias voltage.

Once used in certain radios these diodes are still available to find though they are. Germanium diodes have a lower forward drop voltage of 03v compared to more common silicon diodes forward voltage of 07v.
