Because the voltage drop across the zener diode is constant, the diode is generally used as a voltage regulator. Any device or devices connected in parallel with the zener will have the same voltage applied. Anode Cathode Objectives After studying this unit, the student should be able to: ❯❯ Discuss the operation of a zener diode. ❯❯ Draw the schematic symbol for a zener diode. ❯❯ Construct a voltage regulator using a zener diode. ❯❯ Discuss the operation of a tunnel diode.A linear voltage regulator provides a tightly controlled DC output, which it derives from an unregulated or poorly regulated DC input. The DC output remains constant regardless of the load on the regulator (within specified limits). It is a cheap, simple,

and.extremely robust component. There is no single schematic symbol for a linear voltage regulator. The general physical appearance ofa commonly used type of regulator, rated for an output of around 1A DC, is shown at Figure 191.Figure 510 — The schematic symbol for a Zener diode is shown at A. B is an example of how Zener diodes are used as voltage regulators. manufactured to safely withstand the avalanche current. Since the current in the avalanche region can change over a wide range while the voltage stays practically constant, this kind of diode can be used as a voltage regulator. The voltage at which avalanche occurs can be controlled precisely in the manufacturing process. Zener diodes are Figure 422 shows the schematic symbol

The operational amplifier or “op amp” is widely used for dc and audio circuits as an inexpensive source of gain. Linear voltage regulators are used to maintain a power supply output at a constant voltage over a wide range of currents. Digital ICs operate with discrete values of voltage and current that represent “0” and “1”, (Eln) 100Vdc +o — vw 30 V Anode , Cathode 12 V 6.8 V (A) 1 +30 V +30 V foJ +42 V +12 V Load Side +48.8 V +6.8V _L_ ZenerDlode Voltage Divider/Regulator (B) Figure 61 1 — The schematic symbol for a Zener diode Is shown at A.
