Diodes - Zener - Single

The 1PGSMA4753HR3G Zener Diode is a single breakdown voltage device with a 8V reverse voltage rating. It is designed for high voltage and current applications. It is used primarily for voltage regulation and current limiting in applications requiring an isolation capability for the rectified outputs.

Application Field

The 1PGSMA4753HR3G diode is typically utilized in high voltage and current applications. For example, it can be used in automotive circuits, motor drives, regulation, and over-voltage protection systems. It can also be used in DC-DC converters and the design of power supplies. Additionally, it can be used in the construction of high-efficiency LED lighting and lighting control systems.

Working Principle

At a certain reverse voltage, the 1PGSMA4753HR3G diode will enter breakdown state and start to conduct. The current through it is independent of the applied voltage, and a negligible voltage drop persists across the diode. This effect is called Zener breakdown, and the voltage at which this occurs is the Zener voltage. The Zener voltage is "tuned" and controlled by the design of the diode, allowing it to be used in a variety of applications.

The 1PGSMA4753HR3G diode has a wide operating temperature range and high surge current handling capability. Additionally, it is designed to withstand a maximum peak repetitive reverse voltage of 8 V. This makes it an ideal choice for applications requiring high current, high temperature, and stable voltage regulation.

The Zener diode is a simple and reliable device capable of conducting large currents at low forward voltages. It can be used in low voltage and high current applications, as well as for providing a stable voltage reference in DC-DC converters. Additionally, it can be used for voltage and current limiting, and for providing electrical isolation in power supplies.
