TVS - Diodes are an electronic component, also known as transient voltage suppressor, used to protect electrical circuit from voltage spikes and lightning induced surge. The CPDUR24V-HF is a type of TVS – Diode, which is especially designed to protect sensitive electronic devices from destructive overvoltage damage. The CPDUR24V-HF application fields and working principles will be discussed in detail in this paper.

Typically, CPDUR24V-HF diodes are used to protect circuits from inductive overvoltage spikes caused by motors or other power inductors, usually in the range of 24 volts to 600 volts. The device can provide a low clamping voltage of typically 25V, thus it is suitable for applications with an operating voltage of 24 volts or lower. Another CPDUR24V-HF application is that it can be applied for protection of automotive switches, loud speakers and other sensors against surge voltage from the power circuit.

The CPDUR24V-HF is equipped with an integrated and permanent metal oxide varistor (MOV) load, operating in accordance with the dynamic resistance of its metal oxide varistor. The primary operation of the MOV is to act as a short circuit to protect the device from primary overvoltage. The MOV reduces the clamping voltage of the device, thus resulting in better protection for electronic circuits.

The CPDUR24V-HF types are highly reliable transient voltage suppressors designed with a special high-speed switching transistor and a high temperature-resistant transistor to manage and prevent inrush current from affecting the performance of the device. The device has an excellent surge and surge current handling capacities, so it can effectively protect equipment from overvoltage damage.

Aside from the primary integrated MOV load feature, the CPDUR24V-HF also has a dedicated semiconductor diode. The diode limits the maximum voltage of the CPDUR24V-HF to 25 volts, thus guaranteeing a much higher level of protection against overvoltage damage. This feature is useful for applications where the maximal operating voltage is below 25 volts.

Moreover, the CPDUR24V-HF also contains a chip package with an internal heat sink. This heat sink reduces the power dissipation of the component, so it allows for greater power handling capability. The CPDUR24V-HF also has an overcurrent cut-off system, which automatically cuts off the power supply should an overcurrent situation occur.

In conclusion, the CPDUR24V-HF is a highly efficient and reliable TVS - Diode designed for protection of sensitive electronic devices from destructive overvoltage damage. The device is capable of low clamping voltage and has an integrated and permanent metal oxide varistor (MOV) load, as well as a dedicated semiconductor diode. All of these features make the CPDUR24V-HF a great choice for applications where protection of sensitive electronic components is a priority.
