Diodes - Zener - Single

PDZ22BGWX is a single so called Zener diode. Such a diode was first described in 1934 by a physicist named Clarence Zener. As a diode the PDZ22BGWX conducts current in one direction only, that is when a positive voltage is applied to the anode (i.e. positively charged electrode) of the diode, than current flow through it, while no current can flow when a negative voltage is applied to the anode. With two oppositely charged electrodes a diode is basically a switch or valve in a circuit.

The PDZ22BGWX was developed to allow the reverse current. That is when the current passes through the anode, then some current is allowed by the diode to flow through the reverse direction too. This so called Zener voltage regulator is named after the scientist who first described and theorized about this effect.

The working principle of the PDZ22BGWX is based on the electromotive force (EMF) of the diode, which is the voltage necessary for the diode to bypass the current. When a voltage is applied to the diode exceeds the reverse breakdown voltage of the diode, then some current is allowed to flow through the diode in the opposite direction. This is known as zener breakdown.

The PDZ22BGWX is a versatile device which can be used in different applications, mostly in power supply and voltage regulation systems. It can be used to pass or regulate both, DC as well as AC current. It is also suitable for use in electrochemical applications, RF amplifiers and motor control systems. In addition, the PDZ22BGWX can be used to protect circuits against surges by dissipating a large amount of energy when reverse voltage is applied.

Overall, the PDZ22BGWX represents a powerful and integrated technology which combines the advantages of current-limiting and voltage-limiting devices with a low saturation voltage. These features make it an essential component in a variety of circuit applications.
