1 - you can use any diode, Si, Ge, LED, BAT, etc. as each one will give its own flavor, so socket the diodes and try whatever you got. 2 - you can use any NPN Germanium transistor, as they will change the effect slightly. MP38's are a little dark, tesla 104NU71 are a little brighter. so don't be afraid to experiment, but try to keep it less ...

Si Diode vs Ge Diode: Parameters and Uses Comparison

Generally, the threshold voltage of a silicon tube is about 0.5V~0.6V, and the threshold voltage of a germanium tube is about 0.1V~0.2V. 5) Temperature changes have a greater impact on Ge diodes, but less on silicon diodes. Therefore, silicon tubes have better high temperature resistance than Ge tubes. 6) Forward voltage required for diode ...

How to tell germanium from schottky diodes - Page 1 - EEVblog

Small signal germanium diodes like the 1N34A and 1N270 also use the older DO-7 glass package which is larger and easy to distinguish from the smaller glass DO-35 package used by schottky diodes like the 1N5711, 1N6263, SD series, and BAT series and silicon switching diodes like the ubiquitous 1N4148.

Because the germanium diode has a lower forward voltage drop. Schottky diodes have lower forward voltage drop than silicon, though I can't remember if it's lower than germanium. A DMM with a diode function will easily separate them, all three diodes have a distinct voltage. I went through a bunch of boards at one point, and uncovered a lot of

Germanium diode selection - Tripod

In reverse bias, this is effectively infinite and the DMM gives an overflow' display with a good diode. In forward bias, the display is commonly about 650 (mV) for a silicon diode and 300 (mV) or so for germanium. By swapping the leads you can get a fair idea if the device is good and which end is the cathode.

Germanium diode - zxc.wiki

A germanium diode is a diode based on single crystal germanium . This semiconductor material is doped in such a way that a pn junction is created. Flat diodes, tip diodes and photodiodes were manufactured. Germanium diodes have a significantly softer characteristic curve kink that starts earlier (at 0.2 V) than silicon diodes (at 0.55 V).

identification - How to recognize a Germanium Diode

Germanium diodes have a lower forward voltage drop than silicon diodes. Rig up something that puts a little current thru them, and measure the voltage. For example, a 5 kΩ resistor in series with a 5 V supply should do quite well. The current will is limited to 1 mA, and the reverse voltage to 5 V. Neither should hurt any of the diodes you have.

Types of Diodes and Their Applications – 24 Types of Diodes

Schottky Diode. The Schottky diode, named after a German physicist Walter H. Schottky, is a type of diode which consists of a small junction between an N-type semiconductor and a metal. It has no P-N junction. The plus point of the Schottky diode is that it has very low forward voltage drop and fast switching.

The best way I know to test them is out of circuit, using a DMM in the diode mode. A germaninum diode will have about .25 volts forward drop as opposed to a silicon with .6. The schematic certainly looks like an R.F. detector. Germanium diodes are preferred in this application specifially BECAUSE of their lower forward drop.
