A Transient Voltage Suppressor (TVS) diode is an active electronic device used to protect any electronic components in a circuit from high voltage electrical transients. This is done using an array of two or more individual TVS diodes. TVS diodes utilize a reverse biased PN junction to absorb electrostatic discharge (ESD) or limit the peak voltage of a high powered signal.

CPDQC5V0USP-IPHF is an ultra-low capacitance TVS diode for protecting high-speed data lines from voltage transients induced by ESD (electrostatic discharge). This device has dual channels with one having the capability of operating at peak pulse power of 17.8W, while the other can reach up to 11.6W. It utilizes a SOD-323 plastic package with 0.5mm profile and is rated for operating temperatures ranging from -55℃ to 150℃.

The CPDQC5V0USP-IPHF is suitable for a wide application range and can be used in various industries ranging from automotive to consumer applications. This device is designed to protect against ESD up to 2.5kV for air discharge and 8kV for contact discharge. It is also capable of providing protection against high-energy transients such as lightning (IEC 61000-4-5). In addition, this device contains integral ESD protection that helps reduce noise on signals during high-speed data transmissions.

Application Field

This device is widely used in Portable Electronics, USB, HDMI, DVI, DisplayPort, HDBaseT, FireWire, Video/Audio, Automotive, etc., and is designed to provide ESD protection up to 2.5kV for air discharge and 8kV for contact discharge. It utilizes a PN Junction to clamp the voltage transients and limit the maximum peak voltage. This makes it an ideal protection device for high-speed signal transmission lines.

Working Principle

CPDQC5V0USP-IPHF utilizes a dual-channel protection circuit to effectively reduce the voltage surges induced by ESD and other transient pulses. This device is equipped with a self-inactivating protection circuit and uses an internal diode to prevent excessive peak currents from damaging the circuit. When the voltage transient reaches the working level, the diode will activate and the device will absorb the surge and clamp the voltage. This ensures that the voltage level does not exceed the maximum rating and prevents any damage to the components in the circuit. After the voltage transients have been absorbed, the diode will automatically reset to its initial state.

CPDQC5V0USP-IPHF is an efficient and reliable device that is designed to provide protection against voltage transients. Its low capacitance and high surge current capability make it ideal for protecting high-speed data transmission lines. This device utilizes a PN Junction and contains an integral ESD protection circuit to ensure that the voltage spike is clamped and does not exceed the peak voltage rating. This device is widely used in various industries as it can provide reliable and efficient protection against ESD and other transient pulses.
