1PGSMA4749HM2G

Diodes - Zener-Single

The 1PGSMA4749HM2G is single Zener diode with a 5.6V voltage regulation and a maximum power dissipation of 500 mW. It is one of the most commonly used components in applications where over-voltage protection is needed. The main application field for 1PGSMA4749HM2G is in linear regulator applications.

The 1PGSMA4749HM2G can be used for a wide range of applications in a variety of products such as electronic ballasts, power supplies, pneumatic control systems, communication systems, and automotive electronics. It is also commonly used in battery-operated devices such as phones, tablets, cameras, and other portable digital devices.

The working principle of the 1PGSMA4749HM2G is based on the Zener diode, which is also known as the avalanche diode. As voltage is applied to the diode, the energy in the applied electric field begins to break down the depletion region of the crystal. This creates a region of conduction within the crystal which becomes a low impedance path for current flow.

The 1PGSMA4749HM2G is designed to allow a specific amount of current to flow when the voltage across the diode reaches the Zener voltage. This ensures that no matter how much voltage is applied to the diode, the current will always be limited to the rated value. This makes the 1PGSMA4749HM2G ideal for over-voltage protection.

In addition to over-voltage protection, the 1PGSMA4749HM2G can also be used as a reference voltage source. When a specific voltage is desired, the 1PGSMA4749HM2G can be inserted in series with the voltage source and will act as a voltage reference, allowing only a predetermined amount of voltage to flow through the circuit. This can be used to set a specific operating voltage, or as part of a voltage regulator circuit.

The 1PGSMA4749HM2G is a high quality component and is designed to last for many years. Its 500 mW power rating makes it suitable for even the most demanding applications. With its wide range of application and its excellent performance, the 1PGSMA4749HM2G is an excellent choice for any application in need of over-voltage protection or voltage regulation.
