ATV15C480J-HF Circuit Protection

The ATV15C480J-HF belongs to TVS - Diodes, which is a kind of transistor- bilateral switch, which has anode and cathode and is a semiconductor device with bidirectional conduction. It can clamp the voltage to protect the equipment when the overvoltage exceeding its breakdown voltage.

The application field of the ATV15C480J-HF, mainly includes computers, peripherals, network systems, audio video products, communications, automotive, military, medical equipment, industrial machine, set-top box, household appliances, etc. In these sub-fields, these TVS - Diode can function so as to prevent the overvoltage and overcurrent to cause permanent damage to the circuit.

The ATV15C480J-HF works in principle of normal conduction – (when applying a voltage across its terminals which is lower than its breakdown voltage, the ATV15C480J-HF behaves as an almost perfect conductor) and breakdown or clamping conduction (when a larger voltage is applied across the terminals, the current does not flow until the voltage reaches the breakdown voltage). Each of the conduction and breakdown processes is fully reversible and the switch behaves like a normal transistor in either condition.

It is a Surface Mounted Device, fabricated using advanced high voltage semiconductor processes and state-of-the-art sub-micron lithography. Compared with similar products, the unique shape and fantastic properties of the clamping diode, make them more preferred by customers.

Additionally, the ATV15C480J-HF utilizes a patented dynamic discharge circuit that monitors and controls the clamp current. This gives protection in case of repetitive surge and ESD discharge. This TVS –Diode includes a reverse-biased Zener diode and a low capacitance clamping structure, significantly reducing clamping voltages and clamping loss. Moreover, its design provides good clamping performance even at higher peak current.

In general, the ATV15C480J-HF TVS –Diodes provides a necessary safety feature, with applications ranging from overvoltage suppression for mobile phones all the way to medical device. It can be used in many applications that require overvoltage/overcurrent protection. The fast response time and low capacitance make it an excellent choice for transient protection and help designers protect their products from damage from electrostatic discharge and power surges.
