TVS (transient voltage suppressor) diodes are used to protect electrical and electronic systems from specific overvoltage characteristics. The ATV15C8V0JB-HF is a surge protection diode, a type of TVS diode. It is designed to protect sensitive components from destructive voltage transients typically associated with lightning, power cross, and other causes. In addition, the ATV15C8V0JB-HF also helps prevent false triggering of solid-state relays.

The ATV15C8V0JB-HF is an unidirectional TVS diode that is designed to handle high surge currents exceeding 100A. It features a surge current capability of 8kA, a voltage rating of 15volts, and a storage temperature range of -55°C to +150°C. It comes in an ultra-small, space-saving SOT-666 package (2.5mm x 2mm x 0.65mm) and is compliant to RoHS, AEC-Q101, and Green standards.

The ATV15C8V0JB-HF can be used in a variety of applications, such as automotive electronic components (including electronic ignitions, electronic fueling systems, powertrain systems, start/stop systems, and lighting control systems), consumer electronics, industrial equipment, and medical equipment. In addition, it is also suitable for any application requiring high voltage protection for sensitive components.

The ATV15C8V0JB-HF has several key features. It has a low reverse leakage current (5μA Max), a low dynamic resistance (1.2V at 3A Max), and a low capacitance of 8.1pF Max. It also has a low turn-on voltage drop of 8.3V±1V @ 4A. It has a working reverse voltage up to 14V, a peak pulse power of 2.1kW, and a peak pulse current of 8kA.

The ATV15C8V0JB-HF uses a two-stage protection mechanism to protect sensitive components from voltage transients. In the first stage, the normal flow of current is blocked when the voltage exceeds a certain level. This is achieved by rapidly turning on the TVS diode. In the second stage, when a voltage overshoot occurs, the current output of the TVS diode decreases to minimize the voltage rise, thus preventing the overvoltage from damaging the sensitive components.

Overall, the ATV15C8V0JB-HF is an ideal solution for applications requiring high surge current protection and low breakdown voltage. It is ideal for automotive, consumer, industrial, and medical applications due to its low capacitance, small form factor, low leakage current, and low dynamic resistance. Additionally, its two-stage protection mechanism ensures that it effectively protects the connected components from voltage transients, making it a reliable and robust solution.
