TVS – Diodes

Transient Voltage Suppression (TVS) diodes are semiconductor devices designed to protect sensitive electronic components from adverse spikes in voltage. They are a type of diode that is designed to protect against transient voltage surges. They can be thought of as electronic “fire extinguishers” that protect electrical components from brief surges of energy that can occur from power line or lightning strikes.

CPDH3V3UP-HF Application Field and Working Principles

The CPDH3V3UP-HF is a reliable and robust Transient Voltage Suppression (TVS) diode designed for use in low voltage applications. This high frequency (HF) device combines a guarantee of high reliability with a low level of loss over the range of up to 3V. The CPDH3V3UP-HF is well suited for use in consumer and automotive electronics, industrial, medical, and communications systems.

The CPDH3V3UP-HF is designed to protect sensitive electronic components against a wide range of transient voltages. It utilizes a combination of a Zener diode and a TVS diode. When the external voltage exceeds the breakdown voltage of the Zener diode, the Zener diode becomes reverse-biased and starts conducting, diverting the surge current to the internal TVS diode. The TVS diode then absorbs the excess energy and dissipates it as heat. Once the transient voltage event has concluded, the CPDH3V3UP-HF will return to its non-conductive state and remain in a low power standby mode until the next such event.

The CPDH3V3UP-HF is designed to provide the ultimate protection against ESD, transients, and voltage overshoot on power and signal lines. It is rated to handle pulse currents (Ipp) up to 3000 A (10/1000 μs) and pulse energies (Epp) of up to 60J (10/1000 μs). It also offers excellent diodes characteristics (low forward voltage and low reverse leakage current) and high reliability (UL94V-0 flame retardant plastic encapsulation).

The CPDH3V3UP-HF is designed to be a reliable and robust device that is easy to use. It can be used as a single device in a line board, also it can be combined with varistors, diodes, resistors, capacitors, and inductors in a single board design to provide multiple protection levels. It also provides excellent ESD protection on all lines and due to its low power characteristics it is ideal for use in battery powered devices.

In addition, the CPDH3V3UP-HF offers a wide range of characteristics which make it ideal for use in high frequency applications. It has low capacitance values allowing it to operate with switched mode power supplies with low EMI noise levels. In addition, the device\'s low diode forward voltage drop and low reverse leakage current ensure that power losses are minimal during normal and transient conditions.

The CPDH3V3UP-HF is an ideal choice for providing long-term protection for sensitive electronic equipment from transient voltage events. Thanks to its high reliability, robust construction and excellent ESD and transient voltage protection capabilities, it is well suited for use in a range of applications. Whether it is used in consumer electronics, automotive electronics, medical, industrial or communications systems, the CPDH3V3UP-HF can provide superior performance and long-term protection.
