The Zener diode operates just like the normal diode when in the forward-bias mode, and has a turn-on voltage of between 0.3 and 0.7 V. However, when connected in the reverse mode, which is usual in most of its applications, a small leakage current may flow.
How much voltage can a Zener diode regulate?
The Zener diode operates just like the normal diode when in the forward-bias mode, and has a turn-on voltage of between 0.3 and 0.7 V.
Does a Zener diode reduce voltage?
A Zener diode's design has the special property of reducing a reverse voltage to a specified value. This makes Zener diodes good, low-cost voltage regulators. To use one in a circuit, you calculate a resistor value, then connect the resistor and Zener across the voltage you want to regulate.24 abr 2017
What is a 5v1 zener diode?
This 1N4733A zener diode is set at 5.1V, making it ideal for protecting the inputs of a 5V circuit. specifically, it has a minimum voltage of 4.845 V and a maximum voltage of 5.355 V, with a leakage current of 1 V and a test current of 49 mA. Features: Voltage - Zener (Nom) (Vz): 5.1VDC.
What happens when you connect two Zener diodes in series?
Ensure that this value is not exceeded. Furthermore, if two Zener diodes with different Zener current specifications are connected in series, one of them will not exhibit the specified Zener current and thus the specified Zener voltage.
