Introduction of ATV15C190J-HF

The ATV15C190J-HF is an ESD protection diode, which belongs to two-terminal Transient Voltage Suppressor (TVS) diodes that are manufactured by Littelfuse. This device is designed and constructed to protect electronics from ESD (electrostatic discharge) related transients, spikes, surges or any voltage surge up to its rating of 15kV. It is able to handle excess voltage and offer superior high-energy pulse protection over a wider temperature range.

Application field

The ATV15C190J-HF ESD protection diode is used primarily in field applications that require maximum protection in extreme electrical conditions. For example, it is widely used in industrial electrocardiography equipment, MRI scanners, medical instrumentation, police radars, CATV systems, broadcasting systems, and military equipment. Additionally, the ATV15C190J-HF is used as high-speed protection against ESD pulses that may occur in automotive, consumer electronics, solar energy systems, power systems, and output ports in high-speed data systems.

Features and Benefits

The ATV15C190J-HF ESD protection diode provides superior high-energy pulse protection over temperature (-55°C to 150°C). The device also delivers a greater repeat pulse energy capability than traditional ESD protection designs. The ATV15C190J-HF’s ultra-fast response time also helps reduce accidentally induced voltage breakdowns. Additionally, it provides excellent surge handling capability and offers a wide range of ESD protection levels (2.5kV, 5kV, 10kV, 12kV and 15kV).

Operating Principle

The operating principle of the ATV15C190J-HF ESD protection diode is based on a breakdown mechanism. In normal operation, the diode has a reverse leakage current of less than 1μA resulting from a small reverse bias voltage(Vr). When the diode is subjected to a high electric field, the diode breakdown, characterized by a sudden increase of current flowing through the diode, occurs at a certain voltage (Vb).As the reverse bias voltage (Vr) increases, the diode will pass more current until eventually the breakdown current is reached (Ib). The breakdown voltage (Vb) is usually referred to as the reverse breakdown voltage and is typically the device\'s rated working maximum reverse voltage.

Conclusion

The ATV15C190J-HF ESD protection diode is designed to offer superior high-energy pulse protection over a wide temperature range and is widely used in a wide variety of field applications where maximum protection is required. The device\'s fast response time, excellent surge handling capability and wide range of ESD protection levels make it an ideal choice for electronics that need reliable protection against ESD events. It achieves its superior performance through a breakdown mechanism that releases a large current when subjected to overvoltage or overcurrent situations.
