1N5251B-TR Application Field and Working Principle

Diodes - Zener - Single

A 1N5251B-TR is a single Zener diode manufactured by Microsemi or On Semiconductor. Zener diodes are built to be able to withstand large voltages of up to several hundred volts, and the 1N5251B-TR is designed to have a breakdown voltage of 5.1V. Since they are able to withstand high voltages, they are used in applications where a higher breakdown voltage than an ordinary diode is required.

Zener diodes are used as voltage regulators that act as a one-way current. When a voltage is applied to the diode, it allows current to flow in the forward direction and the voltage applied is reduced. When the voltage across the diode exceeds the Zener breakdown voltage, then the current begins to flow in the reverse direction, and the diode acts as a static diode, functioning as a voltage regulator. In this way, the voltage in the circuit will remain constant, even when the supply voltage varies.

The 1N5251B-TR can be used in applications such as protecting sensitive circuits from high voltage overloads, or it can be used as a voltage regulator in power supplies and other regulated voltage circuits. In addition, since it has a breakdown voltage of 5.1V, it can also be used in the place of a regular diode for current rectification and signal switching.

Its voltage rating is 5.1V at 80mA, and the maximum power dissipation is 300mW. For its maximum reverse voltage, it can withstand 40V at 80mA. Because of its small size and low cost, they are ideal for consumer applications such as TVs and audio equipment, computers, and cell phones.

In conclusion, the 1N5251B-TR is a single Zener diode that is designed to have a breakdown voltage of 5.1V. It is mainly used as a voltage regulator in applications that require a higher breakdown voltage then an ordinary diode, such as protecting sensitive circuits from high voltage overloads or providing constant voltage in power supplies. Its voltage rating is 5.1V at 80mA, and its maximum power dissipation is 300mW. It is smaller and cheaper than many other types of diodes, making it ideal for consumer applications such as TVs and audio equipment, computers, and cell phones.
