The GLL4748A-E3/97 is a Zener diode with single junction and is most often used for protection and regulation purposes. This specific diode is encapsulated in a 3-pin SOT228 through-hole package, allowing for easily detectable physical presence when repaired or maintained. It\'s a reliable component, making it a smart choice for applications prone to accidental component mishandling or rough usage. In addition, its resistance to temperature variation and low noise characteristics further increase durability and reliability.

This diode is part of a class of diodes that are used in a variety of applications. This specific model works by providing protection against overvoltage. It also works as a voltage regulator enabling a steady, consistent output. One particular application field of a Zener diode such as the GLL4748A-E3/97 is a voltage regulator supplied with AC or DC input. It prevents surges in the output and can adjust the output voltage within a certain range.

The diode works by applying a reverse bias voltage on the junction. This voltage causes a depletion of the electrons in the P side and a depletion of the holes in the N side. As the voltage is increased, the P side electrons and N side holes are pushed into the depletion layer which acts as a barrier.

As the reverse bias voltage approaches the Zener voltage, the P side electrons and N side holes are no longer able to pass through the depletion layer. The depletion layer then becomes a thin conducting path, allowing a small current to flow. The Zener voltage is the breakdown voltage at which the diode breaks down and the current starts to flow.

This device has a reverse breakdown voltage at 5.1 V and a maximum continuous forward current of 250 mA. It also has a maximum reverse current of 200 μA at 5.1 V reverse bias. The GLL4748A-E3/97 has an operating junction temperature between -55°C and 125°C and a storage temperature range from -55°C to 150°C.

In addition to its use in voltage regulation and protection, the GLL4748A-E3/97 is also used in ripple filtering circuits as well as other applications where stable output voltage is needed. It\'s a great choice for many electronic components, making it a reliable and effective device.
