The TZM5238C-GS18 is a Zener diode, a component with semiconductor junctions which allow current to flow in only one direction and serve as a voltage regulator or reverse voltage constructor when properly connected. It is a single diode, where all other diodes in this component use a pair of devices.

The TZM5238C-GS18 has a low allowance of reverse leakage current, and a maximum power dissipation of 500mW. Its voltage regulator characteristics ensure no output voltage exceeds the breakdown voltage. Its maximum alternating voltage is 18V and its maximum repetitive peak reverse voltage is 25V.

The application field of the TZM5238C-GS18 is mainly that of regulating voltage. A typical application involves connection in series between the input and output of a DC power supply. This Diode Zener acts as a clamp and prevents the amount of power reaching the load from exceeding a certain level.

The reverse voltage capability of the TZM5238C-GS18 defines its working principle. When a certain voltage level is reached at the anode, the Zener diode\'s conduction path is triggered by an avalanche of electrons. This causes both electrons and holes to be swept in order to reduce the voltage across the device. This reduces the forward voltage across the load, bringing it back to the desired level.

The TZM5238C-GS18 assists in saturating the current at a predetermined level while maintaining a constant voltage. At the same time, it allows the reverse current to pass back to the input, when the output voltage is too high, thus protecting the load from over-voltage conditions. This diode can be operated from -65°C to 175 °C.

In summary, the TZM5238C-GS18 single Zener Diode is mainly used for the application of voltage regulation and clamping of voltage. With its low leakage current and high power dissipation, it can serve reliably in a wide temperature range.
