32+ Zener Diode Schematic Symbol Pictures. Zener diode is a specially doped special typer of diodes used in various applications in electronics circuits mainly it provides stable voltage output across the we know what is zener diode and what is the basic principle of operation of it. Zener diodes are manufactured with a great variety of zener voltages and some are even variable.
Figure 1.53(c) shows the schematic symbol for a varactor.
