Diodes - Zener - Single

The 1N5261C-TR is a type of Zener diode, which is a two electrode electronic component that uses a reverse biased voltage to regulate a current flow. This type of diode is frequently used as a voltage regulator or as a feedback element in many applications such as television sets, radios and various industrial equipment.

The 1N5261C-TR has the ability to handle up to 1 watt of continuous power at d-case (dual-in-line) type packages with a working operating temperature of -55 to +125 degrees Celsius. The most common application for this type of diode is for providing a fixed voltage in power supplies and voltage regulators.

When a current passes through the diode, due to its lower forward voltage drop than a resistor, it acts as a voltage regulator. This means that the voltage across the diode remains constant, regardless of the current through the diode, allowing it to be used as a voltage reference across a range of currents. It also has the ability to limit surge currents, which is useful in many applications that often have high transient currents, such as motor and transformer start-up circuits.

The Zener breakdown voltage is the most important parameter of the 1N5261C-TR, since it determines the precise operation of the device. The breakdown voltage is the voltage at which the diode begins to conduct current in the reverse direction. This voltage is often called the clamp voltage and is normally chosen to be higher than the expected voltage of the circuit.

Zener diodes are available in a range of voltages that range from 1.8 to 200 volts. 1N5261C-TR is most commonly used in applications that require a steady voltage of 6.2 volts with a maximum reverse voltage of 6.8 volts. This particular device has a maximum power dissipation of 500 mW, with a nominal Zener impedance of 8ohm and a maximum forward voltage drop of 0.7V; allowing it to be used with a wide range of currents.

The maximum power dissipation of the diode is an important factor to consider, as the temperature and current load can affect the diode’s performance. When selecting a diode, the power dissipation should be considered carefully as it must be able to handle the worst case power load of the application.

Therefore, the 1N5261C-TR can be used as a voltage regulator, current limiter, or feedback element in a variety of applications. It is important to select the diode carefully for the application and to verify the exact break down and maximum power dissipation and currents of the diode. Also, by understanding the working principle and the application field of the diode, engineers will be able to choose the most appropriate diode for their project.
