Schottky diodes are able to switch between conducting and non-conducting states much faster than conventional diodes. This fast switching speed is the identifying characteristic of a Schottky diode. They are also referred to as hot-carrier diodes. When the circuit is working properly, the output voltage equals the zener voltage and the resistor current is constant.
When the output current increases the zener current decreases. If too much current is drawn from the output, the zener current goes to zero, the zener turns off and the output voltage drops below the zener voltage. Zener regulator design Power dissipated in the zener is Iz times Vz. It is a maximum when the output current is zero. The smaller R, the more output current the circuit can provide. The minimum R is determined by the maximum power that can be dissipated in the zener. There is a tradeoff between power dissipation and output current.
Example 3. The maximum power that can be dissipated by the zeners that are available is 1W. The radio requires a maximum at of 0. Note that the voltage from a car battery may actually vary over the range 12 to The value Zener problem What is the maximum output current at 5V? How much power must the zener diode dissipate?
