A 1N5998B is a Zener diode typically used in a silicon epitaxial planar bright junction construction. It is used to protect against electrical surge and provide regulation. It is a voltage regulator diode with a 5.6V breakdown voltage and a 200mW power dissipation rating.

The 1N5998B is typically used in applications where a regulated voltage is needed or where electrical surge protection is required. This includes in telecommunications or broadcast systems, for power supplies and for automotive applications. It is also used in laser diodes.

The working principle of the 1N5998B is based on the Zener effect. When a reverse-bias voltage is applied to the Zener diode, a certain voltage threshold is reached. At this point, the Zener diode begins to conduct in reverse, allowing current to flow from the anode to the cathode. This ensures a steady, low-voltage drop across the diode, and thus a regulated output voltage.

The 1N5998B has a peak inverse voltage of 5.6V, allowing it to effectively regulate 5.6V of output voltage. It also has a power dissipation rating of 200mW, meaning it can dissipate up to 200mW of energy before becoming damaged. This helps protect the diode from overloads. The 1N5998B is a reliable voltage regulator, and is used in a variety of applications.
