RLZTE-117.5C is a type of single zener diode. It is designed to regulate voltage by allowing current to flow only in one direction, either positive or negative depending on the type of zener diode used. The RLZTE-117.5C device is one of the most reliable and efficient electrical components for protection against surges, over-voltages and even reverse polarity.

A typical diode is made of two p-n junction layers that are each connected to an anode (positive) and a cathode (negative). The p-n junction is the most common type of junction used in semiconductors and is characterized by having a very thin layer of insulation between the two layers. When the anode and cathode are connected, an electrical field is created between them that acts like a dam, allowing current to flow in one direction only. When the zener diode is set under a certain voltage, this field will cause a "zener breakdown", allowing current to flow in both directions, but it is limited by the reverse current, which will protect sensitive components from high voltages or over-voltage.

The RLZTE-117.5C diode has characteristics of both resistors and capacitors. It is a versatile component, with stable parameters, which is used for high voltage and current applications, such as in resonance, snubber and LC filters, DC-DC converters, linear power supplies, switching power supplies, over voltage protection and voltage-controlled current sources. It can also be used as a reverse polarity protection, in applications where the power supply has to withstand reverse voltages up to 500V.

The working principle of RLZTE-117.5C can be explained in three steps. Firstly, when a voltage is applied, the diode starts to conduct electricity and a small amount of current flows through the diode. This current is limited by the zener characteristic of the zener diode, which determines the minimum breakdown voltage of the device. Secondly, when the voltage increases, more current will flow through the diode, until the forward voltage of the diode is reached. Finally, when the forward voltage is reached, a larger current will pass through the diode, until the diode reaches the breakdown voltage. At this point, the current will be limited and the diode will act as a variable resistor, allowing only a certain amount of current to flow.

In conclusion, the RLZTE-117.5C diode is a versatile electrical component that has reliable characteristics and is used in a variety of high voltage and current applications. It is able to withstand reverse voltages up to 500V, and has a zener characteristic of 117.5V, meaning it is suitable for voltage-controlled current sources applications. The working principle can be described in three steps, which include the minimum breakdown voltage and the forward voltage of the device.
