Zener Diode

Zener-Diode Voltage-Regulator Circuits 1 The Zener Diode Zener-Diode Voltage-Regulator Circuits 1 The Zener Diode * Zener diode is designed for operation in the reverse-breakdown region. * The breakdown voltage is controlled by the doping level (-1.8 V to -200 V). * The major application of Zener diode is to provide an output reference that is stable despite changes in input voltage – power supplies, voltmeter,…

2 Zener-Diode Voltage-Regulator Circuits 2 Zener-Diode Voltage-Regulator Circuits * Sometimes, a circuit that produces constant output voltage while operating from a variable supply voltage is needed. Such circuits are called voltage regulator. * The Zener diode has a breakdown voltage equal to the desired output voltage. * The resistor limits the diode current to a safe value so that Zener diode does not overheat.

3 Load-Line Analysis of Complex Circuits * Use the Thevenin Equivalent
