1N60P Germanium Diode – Datasheet. 1N60P is a point contact diode employing N-from Germanium and gives an efficient and excellent linearity when used in TV image detection, FM detection, radio, AM detection etc.

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 ...

The 1N34A Germanium diode is an old standby in electronics. Widely used for detecting the rectifying efficiency or for switching on a radio, TV or stereo etc. Note: These are PN junction silicon types and NOT point contact germanium. Check …

In the pursuit of authenticity, germanium diodes are being ordered, examined and used. I already have some 1N60 from a Chinese eBay seller, just in cases I needed to do some fine signal detection (and to change from the Schottky)

The ideality factor, n, relates to recombination sites in the space charge region. A diode that's free of recombination defects will have an ideality factor of 1. As the number of defects go up (i.e. doping with gold), the diodes ideality factor tends towards 2. This value has no relevance to the type of material used.

Point Contact Germanium Diode Description: The 1N34A is a point contact diode in a DO7 type package employing N−form Germanium and gives an efficient and excellent linearity when used in TV image detection, FM detection, radio AM detection, etc. Absolute Maximum Ratings: (TA = +25 C unless otherwise specified)

Normal (p-n) diodes The operation of these diodes is the subject of this document. Usually made of doped silicon or, more rarely, germanium. Before the development of modern silicon power rectifier diodes, cuprous oxide and later selenium was used; its low efficiency gave it a much higher forward voltage drop (typically 1.4–1.7 V per

germanium diodes or vacuum tubes may be used to construct signal powered frequency doublers. The best choice is usually schottky barrier diodes which reliably exhibit low flicker noise and fast switching speeds in addition to a low barrier potential. Hybrid versions are available with a p-n guard ring which enhances the breakdown
