The BZX84C20VLFHT116 is a Zener Diode that belongs to the Zener Diodes - Single Category. This type of diode is designed primarily for regulated power supply applications and it works by providing a low voltage regulated output.

A Zener diode is a diode that is specially designed to exhibit a breakdown voltage at which a disproportionate amount of current starts to flow. This current is normally referred to as Zener current and the breakdown voltage is known as the Zener voltage. The Zener voltage of a BZX84C20VLFHT116 is 20 volts.

The BZX84C20VLFHT116\'s conduction is reversed biased meaning the current flows in the opposite direction of the normal arrow direction. This reversed conduction is enabled by building the diode with a thin oxide layer in its PN junction. The thin oxide layer enables current to flow from the P-type material to the N-type material which eventually causes the diode to break. At this moment, the BZX84C20VLFHT116 has very little resistance allowing a high Zener current to flow.

The Zener current is limited due to the device\'s own characteristics. It is an inherent limitation of a Zener diode and it applies to both the current and the voltage. In addition to this, the BZX84C20VLFHT116 also features internal heating which further limits the current flow. This internal heating protects the device when the Zener current is too high.

The BZX84C20VLFHT116 has many applications. It is used in some regulated power supplies as a voltage regulator which means it is capable of maintaining a steady output voltage irrespective of the output current. This type of diode is also used to test the reverse breakdown voltage of other components such as rectifiers, P-N junction diodes, and transistors. This can be done by connecting a BZX84C20VLFHT116 in series with a component and supplying it with a voltage higher than the Zener voltage.

This type of diode is also used as a shunt regulator to protect circuits from overvoltage. It is connected in parallel with the circuit and it helps to maintain a specific level of voltage. In this configuration, the diode controls the voltage by absorbing or dissipating excess current, depending on the direction of the current.

The BZX84C20VLFHT116 is also used in Zener voltage references, which is a type of circuit that includes a voltage regulator, operational amplifier, and a Zener diode. The operational amplifier amplifies the difference between the supplied input voltage and the Zener voltage, while the Zener diode controls the voltage based on the feedback from the operational amplifier.

In summary, the BZX84C20VLFHT116 is a Zener diode with a Zener voltage of 20 volts. It can be used in many applications such as regulated power supplies, testing and diagnosing other components, shunt regulation, and Zener voltage references. The device has a very low resistance at a specified breakdown voltage and is capable of absorbing and dissipating current in order to maintain a set level of voltage.
