Diodes - Zener - Single

The 1PGSMA4748M2G is a Zener Diode type of single component device. This device is typically used when a voltage signal needs to be regulated or stabilized. This type of diode is most often used as a voltage reference component in an electronic circuit to maintain a certain voltage level.The 1PGSMA4748M2G Zener Diode is made up of a semiconductor material, such as silicon, on which a thin layer of an impurity has been added to produce a rectifying junction. An external voltage applied across this type of diode has a “knock-on” effect which works to breakdown this rectifying junction, allowing a controlled flow of current to pass. This current is then used to maintain a specific voltage level.This diode\'s application field ranges from positive voltage regulators to voltage references, voltage stabilizers and surge suppression applications. It is also used for temperature compensation circuits and for specific power supply applications.The working principle of the 1PGSMA4748M2G Zener Diode is based on the fact that the reverse breakdown voltage of this component can be precisely controlled. When the reverse potential of the component rises to a certain value, called the Zener voltage, a very small current called the Zener current flows through the diode and keeps a certain voltage level stable. This current flow is kept very controlled and low, ensuring the desired voltage level is kept stable.It is also important to note that the 1PGSMA4748M2G Zener Diode has a certain forward voltage drop, which is dependent on the current passing through the device. This, however, is much higher in comparison to the relatively low reverse bias voltage (Zener Voltage) used to maintain stability in the desired reverse bias condition. This means that the forward voltage drop of the device must be taken into account when regulating or stabilizing a voltage signal.In conclusion, the 1PGSMA4748M2G is a Zener Diode type device that is used to maintain or stabilize a specific voltage level. It works based on the reverse bias voltage being accurately controlled and its forward voltage drop, these two features help ensure that the desired voltage is maintained at all times. This device has various application fields and as such, is a popular choice amongst engineers in tackling different voltage regulation or voltage stabilization tasks.
