An ideal diode is simply a PN junction where the change from ptype to the ntype material is assumed to occur instantaneously. Silicon and germanium diodes exhibit a cutin voltage of V and V respectively in their characteristic curves and thus approximate closely the ideal diode in this respect.
Oct 08, 2018· Diode Characteristics. When a Ptype material is brought in contact with N type material electrons and holes start recombining near the junction. This results in lack of charge carriers at the junction and thus the junction is called depletion region. When we apply voltage across the terminals of PN junction, we call it as diode.
Regarding the diode, just about any small signal detector diode will work. Real germanium diodes are seldom made any more and tend to be pricey and sometimes variable in .
Sep 08, 2012· For example, RasPi clamps some HDMI data lines between 0V and + or +5V by using two diodes, one that clamps a negative voltage to 0V (actually approx to because of the voltage drop across a Schottky diode) and one that clamps a positive voltage to + to + The two diodes are in the same package to save board space.
The Manual and the Schematic which are both clearly marked for the IT17 both call for a 1N191 Diode. Yes,all tests and voltages were taken with the line control centered on the meter. Hi Alan, Well,so much for following anything the manual says.

Oct 28, 2011· Published on Oct 28, 2011 Germanium point contact diodes are ideal for rectifying high frequency up to the GHz range. In the video I explain how such a diode works.
Oct 30, 2012· It's supposed to sound fizzy...'s germanium. If you put germanium clipping diodes in a tubescreamer type circuit, you will get the same effect, it's like a cross between overdrive and fuzz. I would guess EHX Germ OD is probably closer to a fuzz circuit since it has a bias control.
DIODE IDENTIFICATION. There are many types of diodes varying in size from the size of a pinhead (used in subminiature circuitry) to large 250ampere diodes (used in highpower circuits).Because there are so many different types of diodes, some system of identification is needed to distinguish one diode .
Germanium. Similar to silicon and aluminum, natural germanium compounds tend to be insoluble in water and thus have little oral toxicity. However, synthetic soluble germanium salts are nephrotoxic, and synthetic chemically reactive germanium compounds with halogens and hydrogen are irritants and toxins.

It's MP25A pnp germanium transistor (similar to 2N189) manufactured in USSR in September 1979 (I got bunch of them from ebay relatively cheap) connected as 2nd circuit from article (NAND element), but instead of one diode V4 I put 3 silicon diodes connected in series (the circuit refused to work with 1 silicon diode as V4) and I use 10K ...

Oct 09, 2014· Basically, a germanium diode responds in the same way any other diode responds. As you increase the temperature, the intrinsic carrier concentration increases. This pushes the fermi level closer to the intrinsic fermi level (the middle of the band gap).
