Looks like you’ve clipped this slide to already. A typical application might be as above: A 10 V Zener diode (type 1N4740) is placed in series with a resistor and a fixed 12 V power supply. The resistor value is chosen such that several mA flow through it and through the Zener, keeping it in its breakdown region. Diodes and Diode Circuits TLT-8016 Basic Analog Circuits 2005/2006 2 3.1 Diode Characteristics Small-Signal Diodes Diode: a semiconductor device, which conduct the current in one direction only. Data about a diode is presented uniformly for many different diodes. 23 Fig. Fig. See our Privacy Policy and User Agreement for details. This paper. The application of triode created a new era in broadcasting with the invention of the crystal radio sensor by Pickard, 1912. Zener diodes are used to maintain a fixed voltage.
