TVS-Diodes, also known as Transient Voltage Suppression Diodes, are devices designed to protect sensitive electronic components from damage, such as those caused by voltage spikes, power surges and Electrostatic Discharge (ESD). CPDFR5V0-HF are a type of TVS Diodes designed to protect sensitive components against high-voltage, high-frequency transients.

CPDFR5V0-HF are a bidirectional, low-capacitance, fast-acting surge-protection diode with a peak pulse power of 5W (2/10 µs), a peak pulse current of 800A (8/20uS) and a working voltage from 5V - 400V @ 500MHz. They are used in applications where EMI/RFI filtering is needed, such as industrial equipment and telecom applications. The high-frequency safety isolator feature helps to reduce circuit noise and interference.

The working principle of CPDFR5V0-HF is simple: when a voltage surge is encountered, they act as a clamp and reduce the voltage. The built-in capacitance helps the diode to absorb and dissipate high-frequency noise, while the bi-directional diode structure helps to ensure that the voltage is clamped on both the positive and negative sides of the voltage spike. The built-in surge protection circuitry further helps to reduce the effects of voltage surges and comprehensive over-voltage protection.

CPDFR5V0-HF are also designed with thermal protection. The presence of a self-activating thermal inhibitor will help to protect against thermal runaways, while the wide temperature range (-40°C to +125°C) ensures that the device is suitable for use in a variety of applications. Furthermore, the low-impedance, fast response time helps to ensure that the device will respond quickly to voltage surges, protecting the connected components in the process.

In addition, the CPDFR5V0-HF also features an ESD circuit which helps to protect the device against unexpected static charges. The ESD circuit is designed to react quickly to electrostatic discharges, reducing the amount of energy that is absorbed. Its low capacitance also helps reduce the amount of EMI/RFI noise entering the system.

In summary, the CPDFR5V0-HF is a fast-acting diode designed to protect electronic components against voltage spikes, power surges, ESD, and EMI/RFI. Its wide operating temperature range, low-impedance, and thermal protection ensures that it can be used in a variety of applications, while its ESD circuit helps to protect against electrostatic discharges. The CPDFR5V0-HF is an excellent choice for protecting sensitive components against various types of voltage transients.
