1PGSMA4762HR3G Discrete Semiconductor Products

Diodes – Zener – Single

The 1PGSMA4762HR3G is a single device which can be classified under diodes – Zener –single. It is developed by Central Semiconductor Corp. and is widely used in different parts of the world. This device is widely used for its multiple capacity power application.

Application Field

The 1PGSMA4762HR3G is mainly used for voltage regulation and consists of a highly doped N-region that acts as a PN junction barrier. It is also used for protecting circuits from a sudden surge in voltage levels and for voltage regulation for low voltage applications. It can be used for both positive as well as negative voltage applications.

Working Principle

The 1PGSMA4762HR3G Zener diode works on the principle of reverse breakdown, or Zener breakdown, at the PN junction. In this applied reverse bias, the depletion region widens and the electrons that get collected at the PN junction are pushed back so that a free path is created. The free path is the most important feature of this device and it is responsible for its voltage regulation. When the applied voltage exceeds the reverse breakdown voltage, the electrons that get collected at the PN junction are drawn away and a continuous current passes through the diode. This is called Zener current and can be calculated from the voltage applied on the diode. As the Zener current increases, the reverse breakdown voltage also increases. Thus, the device can be used to regulate voltage in many applications.

The 1PGSMA4762HR3G is used as a part of other circuits as well. It is especially used in high power switching applications. Here, it helps in providing stable current by providing constant voltage to the current controlling device. In addition, the device can be used as a voltage reference diode in circuits which require regulated voltage supply.
