Sep 11, 2013· Germanium is a stone element with symbol Ge and atomic number 32, that’s used as a semiconductor in transistors and diodes, popping up in a few classic effects like the early period Arbiter Fuzz Face, the storied Dallas Rangemaster and the Maestro Fuzz-Tone. “Subjectively the sound of Germanium offers a smoother, more-ear pleasing
Nov 15, 2017· Germanium is a semi-metallic element that was used to make transistors, diodes, and other components that were widely used in consumer electronics until more consistent and more reliable silicon components became available in the late 1960s.
Both silicon and germanium can be combined with other elements called dopants to create solid-state electronic devices, such as diodes, transistors and photoelectric cells. The primary difference between silicon and germanium diodes is the voltage needed for the diode
2) These devices were primarily transistors and diodes. However, germanium diodes have the advantage of an intrinsically low forward voltage drop, typically 0.3 volts; this low forward voltage drop results in a low power loss and more efficient diode, making it superior in many ways to the silicon diode.
These are high quality germanium diodes made by Telefunken in Germany. Forward voltage is .33-.35. 30v, 15mA. These are nice rare audio diodes. The black glass body is twice as long as a normal DO-7 germanium diode and has TFK and both part numbers printed on it. Price is for 1 piece. These are NOS, in the standard glass DO-7 case.
These results show you that the germanium diode consumes much less voltage than the silicon diode. Again, if you're not using the circuit for temperature-sensitive applications, a lot of current or voltage, germanium diodes could replace silicon diodes, especially for home projects, and especially if you are using low power and need to be very efficient with power.
Silicon Germanium (SiGe) rectifiers Design efficiency and safety through fast switching and extraordinary safe operation area For many circuit designs, the main challenges are integration of more functions per space, design for highest efficiency, and system miniaturization.
Aug 28, 2012· The interesting thing is that when you use a germanium diode to stabilize a germanium transistor, the rising forward voltage on the diode coupled with the rising gain on the transistor is generally a wash. Fun. I try to add the stabilizing diode to any pedal I think I'll care about it on.

Universally useful and adaptable, the transistor is an essential component of electronic circuitry. Wherever you need to control the flow of electricity in a device from transistor radios, to diodes, to circuit boards you can find a great collection of transistors on eBay. What types of transistors
In the stompbox realm, you’re liable to encounter two types of germanium components: germanium diodes, which lend distortion pedals a softer, smoother tone relative to silicon diodes or LEDs, and germanium transistors, which are typically used in clones of ’60s drive and fuzz pedals.
Nov 23, 2019· A transistor multimeter can tell you how much current or voltage goes through a transistor in a circuit. These transistors are used with diodes and semiconductors for letting electricity flow in a certain direction. Identify symptoms when you need to check or replace these elements.
The development of the germanium transistor in 1948 opened the door to countless applications of solid state electronics. From 1950 through the early 1970s, this area provided an increasing market for germanium, but then high-purity silicon began replacing germanium in transistors, diodes
You will need to buy one of item 'GE transistor testing fee' in the germanium transistor category for each transistor you want tested. For matched pairs, you will also need to email me with the gains you want. This is the fee to have germanium transistors tested for gain and leakage. 1 Original Tungsram AC188K PNP high gain Germanium transistor.
Aug 14, 2016· In this post let us see why Silicon Diode is preferred over Germanium Diode . The following table gives us the comparison of Silicon diode vs Germanium diode.. Here the fist four points are advantages of Silicon (Si) based diode over Germanium (Ge) based diode. The last point is the disadvantage of the silicon diode.
Jul 27, 2018· Transistors play a vital part in the design of this effect and their germanium and silicon diodes can sound quite different in the final result. The transistor is considered to be one of the most important inventions of the 20th century, perhaps even, of all time.
Difference Between Diode & Transistor One of the major difference between the diode and the transistor is that the diode converts the alternating current into direct current while the transistor transfers the input signals from the low resistance circuit to high resistance circuit. The other differences between them are explained below in the tabulated form.
Production of semiconductors in the former Soviet Union started in about 1947, and like most countries the first devices were point-contact diodes used as detectors for radar. In the 1950's work moved on to point-contact transistors, and quickly on to junction types, and then silicon transistors.
