A NZX33B,133 diode is a type of single Zener diode component. A Zener diode is a semiconductor device that allows current to flow in both directions when a forward voltage is applied, but once a certain reverse voltage or \'clamping\' voltage is reached, the diode starts to allow larger reverse current to flow. This type of diode is used to regulate voltage levels and can provide electrical isolation between two or more circuits.

The NZX33B,133 diode is rated at 33 volts, with a power rating of 1 watt and a maximum reverse voltage of 135 volts. It is constructed using a silicon substrate and an epitaxial layer on which a N-type diffusion is applied. This N-type diffusion is then heavily doped with an N-type dopant material. The diode\'s doping profile enables a precise Zener breakdown voltage to be achieved. Additionally, its small physical size, low cost and low power consumption make it an ideal choice for numerous applications.

The NZX33B,133 diode has a wide range of application fields. It is commonly used to regulate voltage levels in power supplies, over-voltage protection circuits and AC-DC converters. Furthermore, it can be used to protect circuits against power surges or voltage spikes as well as in electronic ballasts and fluorescent lamps.

The working principle of the NZX33B,133 diode is based on the Zener effect. When a forward voltage (VF) is applied to the diode, current flows through the diode in the forward direction. It is then possible to increase the reverse voltage across the diode until the Zener breakdown voltage (VZ) is reached. At this point, the diode begins to allow current to flow in the reverse direction, while maintaining a relatively low voltage drop. This reverse current is called the Zener current (IZ). The breakdown voltage (VZ) is defined as the voltage at which the Zener current (IZ) is equal to a specified current (IP).

In summary, the NZX33B,133 is a single Zener diode component that is designed to regulate voltage levels, protect circuits against power surges and provide electrical isolation between two or more circuits. It features a wide range of applications, a small size, low cost, low power consumption and a precise Zener breakdown voltage, making it an ideal choice for a variety of applications. Its working principle is based on the Zener effect, which occurs when a specified reverse voltage is reached.
