Diodes - Zener - Single

The 1N5250BTA is a 9.1mW Zener diode with a thermal power rating of 500mW. It has a maximum reverse current of 5mA and a maximum reverse voltage of 5.1V. It is a small signal, ultrafast, low voltage, low current diode.

Application Fields

The 1N5250BTA is useful in a variety of applications. One of its most common uses is as a voltage regulator. By connecting the diode across a voltage source, the diode will regulate the voltage supplied to the load. This can be useful in applications such as over-voltage protection, where an over-voltage event can be prevented, or in voltage limiter circuits. The 1N5250BTA is also popular in low-voltage RF applications, such as FM transmitters. In these applications, it serves as a low-noise signal limiter.

Working Principle

A Zener diode works on the principle of breakdown. When a reverse bias is applied to the diode and the voltage across it reaches a certain level, the diode will start to conduct in the reverse direction. This is known as Zener breakdown. When the diode is operating in the breakdown mode, it will be able to regulate the voltage at the point of breakdown. This is called the Zener voltage.

The Zener voltage of a diode can be changed by adjusting the amount of reverse bias applied to the diode. The 1N5250BTA has a Zener voltage of 5.1V at 5mA of reverse current. The Zener voltage changes with the reverse current, so the voltage will be higher at higher reverse currents. This can be used to set the voltage on a power supply or to limit the voltage on a signal line.

Zener diodes can also be used as temperature sensors. When the diode temperature increases, the Zener voltage decreases. This can be used to monitor the temperature of the diode, or the temperature of a device in which the diode is installed.

Overall, the 1N5250BTA is a versatile component with a variety of applications. It is a great choice for voltage regulation, over-voltage protection, low-voltage RF boards, and temperature monitoring.
