Diodes - Zener - Single

The CDZFHT2RA18B is designed for use as a switching device within an electrical circuit. It is a ‘single’ zener diode, which means that it has only two terminals - a cathode and an anode - and can be used in reverse bias or a forward bias. The CDZFHT2RA18B is able to operate at a maximum voltage of 280 Volts and has a wide operating temperature range of -55°C to 175°C.

Application Field

The CDZFHT2RA18B is primarily used as a protection device against voltage transients in an electrical circuit. Essentially, the component has a relatively low breakdown voltage of 3.6 Volts and therefore if a transient voltage in the circuit rises to that level, the component can be switched on to limit the amount of current flowing through the circuit. This helps to protect the other components in the circuit and the device itself.

This component is also used as a voltage reference diode, which acts as a reference voltage source in analogue to digital converters and voltage limiters. The component can also be used in circuits that require a low power consumption and a high reliability, like in low-voltage supplies and DC/DC converters.

Working Principle

The working principle of the CDZFHT2RA18B is very simple and relies upon the PN junction diode behaviour. The component is essentially a diode, however since it is designed for use as a zener diode, it is manufactured to have a very low breakdown voltage. When the component is reverse biased, the depletion region expands, allowing current to flow from the cathode to the anode if the voltage exceeds the breakdown voltage, i.e. the component has been ‘switched’ on. Conversely, when the forward bias is applied, current flows from the anode to the cathode. In this way, the component can be used to limit voltage in a circuit.

Conclusion

To conclude, the CDZFHT2RA18B is an ideal component for use in electrical switching applications as well as operations where a low power consumption and a high reliability are desired. The component can be used in both forward bias and reverse bias circuits, and depending upon the environment, it has an operating temperature range of -55°C to 175°C. Overall, the component is a good choice for applications where a low breakdown voltage is required.
