TVS or Transient Voltage Suppressor diodes, also known as surge absorbers, are designed to offer short circuit protection. The CPDER24V-HF is a component belonging to this family of transient suppressor diodes. This article will explain the application field and working principle of the CPDER24V-HF.

Application Field

The CPDER24V-HF is specifically designed for protection against electrostatic discharge (ESD) and electrical overstress (EOS) transients from TV sets, VCRs, DVD players, audio equipment, and antennas. The component is capable to withstand up to 24V related impulse from ESD and other fast transients for protection of electronic devices. The component also provides a high speed, low inductance connection to ensure reliable data speed with low noise. It is particularly effective for protecting lines that contain sensitive control signals such as audio, video, and digital signals.

Working Principle

TVS diodes, including the CPDER24V-HF, are designed to shut down and protect sensitive electronic components when subjected to excessively high voltages. This is known as the clamping action. The working principle is simple: as the potential difference reaches a peak, the component conducts current and provides a low impedance path to the ground. This produces an electric charge by dissipating the excessive current or voltage and prevents damage to nearby circuitry.When a transient arises, the clamping action is instantaneous. The CPDER24V-HF can, for example, limit the voltage of a signal line to no more than 24V, thus protecting other components such as inductors, capacitors and transistors from possible destruction.

Conclusion

The CPDER24V-HF is a component designed to protect against ESD and EOS transients from TV sets, VCRs, DVD players, audio equipment and antennas. It is designed with a high speed, low inductance connection to ensure reliable data speed and low noise. The component works through a clamping action which basically consists of providing an electric charge by dissipating the excessive current or voltage, thus preventing damage to other nearby circuitry. For all these features, the CPDER24V-HF is the ideal component to protect sensitive electronic components from high voltages.
