  • Diode Characteristic Curve - Peter Vis

    Non-Linear CharacteristicsJunction DiodeElectron-Hole PairForward BiasThe BarrierCut-Off RegionReverse BiasBreakdown RegionUseful Diode ParametersTemperature DependenceThe Flaming Diode!Crystal RadiosAll of these pretty graphs are indicating one thing. They are indicating that a forward-biased diode is not a linear device. In simple language, the current that flows through it is not proportional to the applied voltage. If you can remember this bit, then you can go to the top of the class.
  • Characteristics of Silicon Germanium Diodes

    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 to

  • how do the silicon diode and germanium diode

    2008-10-1  The shapes of the curves are the same. The difference is the point at which the "knee" occurs on the horizontal axis. They are approximately at the values given by the previous respondent.

  • Forward and Reverse Bias Characteristics of Diode

    Figures 2-4 and 2-5 show typical Forward and Reverse Bias Characteristics of Diode for low-current silicon and germanium diodes. From the silicon diode characteristics in Fig. 2-4, it is seen that the forward current (I F ) remains very low (less than microamps) until the diode forward-bias voltage (V F ) exceeds approximately 0.7 V. Above 0.7 ...

  • Activity: Diode current vs. voltage curves [Analog

    Activity: Diode current vs. voltage curves. Objective: ... For example, at 2 mA forward bias current a low barrier silicon Schottky diode will have a forward voltage of ~0.3 volts while a silicon PN junction diode will have a voltage of ~0.7 volts. This lower forward voltage drop can cut the power dissipated in the diode by more than one half.

  • Experiment No: 1 Diode Characteristics

    2018-1-22  common emitter configuration is the same as the I-V characteristic of a diode. The typical value of V BE for a silicon BJT is 0.7 V. Output characteristics are obtained between the output voltage V CE and output current I C at constant input current I B. The output I-V characteristic consists of a set of curves, one for each value of I B

  • How do diodes and rectifiers differ? - Quora

    Diode A diode is formed by combining a specimen of the P-type semiconductor and N-type semiconductor, and the junction thus formed is termed as PN junction.The majority carriers from one side of PN junction flow through another junction. Rectifier...

  • Crystal Radio Diode - Peter Vis

    2020-5-31  This is a silicon junction small signal Schottky diode. This diode has a 3.8 mm long body. The seller on eBay, for whatever reasons, lists the silicon diode as a "Germanium Detector Diode". However you can tell straight away, because if the body is around 4 mm long then it is not the correct diode.

  • Antique Radio Forums • View topic - EICO 666 1N48

    Note the germanium diode used in the transistor circuit can be replaced with a silicon diode (such as the 1N4148), however it may affect the transistor test results as the silicon diodes have a higher voltage drop, however this is a minimal effect, so if you don't have a germanium diode, you can use the silicon diode

  • Why is silicon preferred over germanium in preparing

    There are several reasons Silicon has become the preferred semiconductor in the present, over Germanium. First reason is that Si forms on its surface very easily a thin layer of SiO2 which is a very good insulator and which technologically can be...
