ATV15C9V0JB-HF Circuit Protection

Transient voltage suppression (TVS) diodes are designed to protect sensitive electronic circuits from overvoltage transients generated by electrical interconnect system interface, inductive switchgear, and other power components in electrical systems. The ATV15C9V0JB-HF is a TVS diode designed to limit the clamping voltage and clamping current to protect a wide range of circuits. TVS diode technology is used in a variety of applications, from industrial to consumer and automotive to aviation and communications.

Application Fields

ATV15C9V0JB-HF is designed for board-level protection to safeguard sensitive electronic components from voltage transients caused by lightning and other transients. This device is suitable for protecting consumer electronic equipment, communications equipment, automotive electronics, medical devices, satellite systems, and other electronics. It can also be used in industrial electronics such as AC/DC converters, solar microinverters, etc. It has an environmentally friendly design, meaning its surface-mount package is RoHS compliant.

Working Principle

The ATV15C9V0JB-HF consists of two components: an avalanche diode and a Zener diode. When transients pass through the device, the avalanche diode allows a high peak of current to pass through while the Zener diode blocks the remaining unwanted voltage from passing through the circuit. When the voltage is clamped to a safe operating level, the Zener diode stops the current and the device returns to its non-conductive state. Thus, the device can protect the circuit from over-voltage transients.

The peak pulse power dissipation of the ATV15C9V0JB-HF is 9 Watts, and its peak clamping voltage is 15 Volts. The device can be used as either unidirectional or bidirectional protection, and it includes an overvoltage protection for electronic equipment. It is available in surface-mount packages, making it suitable for modern electronics designs.

The ATV15C9V0JB-HF is capable of handling large surge current ratings up to 3.5 kA, giving it a high protection level for industrial, commercial, and consumer applications. It is also RoHS compliant, meaning it does not contain any harmful materials such as lead and brominated flame retardants that are hazardous to the environment. The device has a high reliability, and is highly resistant to electrical noise and temperatures up to 125°C.

Overall, the ATV15C9V0JB-HF is a reliable TVS diode designed to provide advanced protection from over-voltage transients. It is an ideal solution for protecting sensitive circuit components from electrical surges caused by lightning and other transients.
