1PGSMA4763HR3G Discrete Semiconductor Products

Diodes - Zener - Single

A 1PGSMA4763HR3G is a single Zener diode designed with a high stand-off voltage capability and noise immunity characteristics that make it suitable for applications in a wide variety of fields. The device is most often used as a voltage regulator, protection device, or reference device. In any application, the Zener diode works by relying on the phenomenon of Zener breakdown. This means that by constructing a diode with a certain junction depletion width, and a high enough voltage, Zener breakdown will occur, allowing current to flow in reverse direction.

When used in a voltage regulator or protector application, a 1PGSMA4763HR3G diode can be connected in series with a load, with the output of the regulator feeding back to the input. This provides a stable output voltage to the load, and acts as a safeguard in the event of any voltage problems. The Zener voltage, along with the series resistive element, determines the various characteristics of the diode.

The 1PGSMA4763HR3G diode is also often used as a reference device. In a reference application, the Zener breakdown process allows a stable, low-noise reference voltage to be generated. This reference voltage is then used to power the other components in a system, such as analog-to-digital converters or other precision instrumentation. The Zener breakdown phenomenon is also used to help create precision level-sensing circuits, temperature monitoring systems, or battery-powered applications.

In addition to its voltage regulation capabilities, the 1PGSMA4763HR3G diode also features noise immunity characteristics that make it suitable for use in high-noise environments. The noise immunity ability is determined by the Zener junction barrier, which screens out any noise signals that may be present on the input voltage. This noise immunity allows the device to be used in rugged and vibration-prone environments, where traditional voltage regulators may fail.

The 1PGSMA4763HR3G diode is a versatile device, and its wide range of applications makes it a popular choice for many electronics and automation projects. Its combination of high stand-off voltage, low power draw, and noise immunity capabilities make it a reliable choice for any type of project requiring a stable and reliable voltage regulator or reference device.
