- A Zener Diode, also known as a breakdown diode, is a heavily doped semiconductor device that operates in reverse. When the voltage across a Zener diode’s terminals is reversed and the potential reaches the Zener Voltage (knee voltage), the junction breaks down and the current flows in the opposite direction. The Zener Effect is the name given to this phenomenon.
- A Zener diode is a heavily doped semiconductor device that operates in the opposite direction.
- This 1N4732A Zener diode comes in a Through-hole package. This type of diode can be used in a variety of circuits, including a simple voltage regulator and a protection circuit. However, it is critical to remember that in any application, this diode must always be connected with a Zener resistor.
- The operating voltage of the 1N4732A 4.7V Zener Diode is 4.7V, and it is used as a reference element within voltage regulation, as opposed to other types of Zener diodes. As a result, it is used in switching and clipper circuits.
Pin Configuration
- The pin configuration of a 1N4732A Zener diode is shown below. This diode has two pins, with each pin and its function described below.
- Pin1 (Anode): The flow of current is always throughout the anode.
- Pin2 (Cathode): The flow of current is always throughout the cathode.
How to use a Zener Diode?
- As previously stated, a Zener diode is most commonly used in a protection circuit or a crude voltage regulator circuit. In any case, it is critical to remember that a Zener diode should always be used in conjunction with a Zener resistor.
- A Zener resistor is simply an ordinary resistor that is used to limit current. This resistor determines (limits) the amount of current that can flow through the Zener diode or the load connected to the Zener diode; the Zener diode is thus protected from high current. A high current will damage the diode if this resistor is not used. The circuit for a simple Zener diode is shown below.
- The formulae for calculating the Zener series resistor Rs in the above circuit are shown below.
- (Vs – Vz) / Iz = Rs
