Diodes - Zener - Single

SMZG3792B-E3/52 is a type of Zener diode, specifically a single zener diode. Zener diodes are used as voltage references or regulators, and are formed from a conventional semiconductor p-n junction. This type of diode has a unique reverse breakdown behaviour, which allows it to be used for voltage regulation, with the diode conducting to keep the voltage at a set level. SMZG3792B-E3/52 has a PIV (peak inverse voltage) of 37V, with a maximum reverse current of 1.0mA, and a peak forward surge current of 63A.

Application

SMZG3792B-E3/52 is used in voltage regulation circuits, mainly in power supplies and regulators. It is often used in series with other components to maintain the output voltage and limit fluctuation, allowing electrical components to run correctly and efficiently. It can also be used to vary the voltage across other components, for example to vary LED brightness, or for noise reduction and filtering.

Working Principle

SMZG3792B-E3/52 is based on the reverse breakdown properties of a p-n junction. This causes current to flow when the voltage reaches a certain level, which is known as the reverse breakdown voltage. When a diode is reverse biased, the electric field within the junction is increased. As the electric field increases, it reaches a point at which it breaks down, allowing a current to flow. The voltage at which this occurs is called the Zener voltage.

SMZG3792B-E3/52 has a Zener voltage of 37V. This means that it conducts and regulates the voltage within the circuit when it reaches 37V. It also conducts in the forward direction, allowing current to flow in a conventional diode manner. It is usually used in series with other components to provide the circuit with a stable voltage.
