The CPDQR5V0HE-HF is a Transient Voltage Suppressor (TVS) diode specifically designed to protect electronic circuits from transients as caused by lightning, electrostatic discharge (ESD), inductive switching, and other sources. This diode is most suitable in aviation, automotive, military, and commercial applications.

The CPDQR5V0HE-HF is a small, low-profile package designed to fit a variety of applications. It is a single component designed for surface mount mounting, and is constructed with an internal large-capacitance silicon diode, connected in a back-to-back configuration between a high power resistor and an inductor in a two-terminal package. The entire assembly is designed to withstand high voltages and maintain a constant reverse voltage-clamping voltage, even when the applied voltage increases rapidly.

The working principle of a CPDQR5V0HE-HF diode is based on the reverse breakdown characteristic of the p-n junction. When an external voltage is applied to the diode, the applied voltage increases the reverse electric field effects which causes the diode to “breakdown” and start conducting current. The diode is designed so that this breakdown voltage is maintained constant across a specified range of temperature and voltage. This constant voltage maintains a stable reverse electric field, which limits the current flow and protects the circuit from high-voltage transient spikes.

The CPDQR5V0HE-HF diode offers a number of advantageous features. It has a fast response time of less than one nanosecond that can handle most lightning, ESD, and inductive switching transients; it is electrostatic discharge (ESD) protected up to 100V, and it is RoHS compliant. Other advantages include its small size and its inherent thermal stability. It is also designed for low capacitance and leakage current, and it is highly reliable in its operation.

The CPDQR5V0HE-HF diode can be used to protect a wide range of electronic circuits from transient voltages. As a reliable, low-profile TVS diode, it is a particularly valuable choice for the aviation, automotive, military, and commercial sectors. Its fast response time and high capacitance make it a great choice for a wide variety of applications where the protection of sensitive circuitry is necessary.
