TVS - Diodes (Transient Voltage Suppressor – Diodes) are electronic components used for protecting electrical and electronic systems from transient overvoltage. They are specifically designed to protect sensitive electronic equipment against voltage surges. The ATV15C180JB-HF is a diode from this family of components and it has specific characteristics and properties that make it suitable for specific applications. This article will explore the ATV15C180JB-HF application field and its working principle.

Application Field

When it comes to the ATV15C180 Series, they are suitable for protecting automotive power lines, data lines, and internal circuits. This particular model, the ATV15C180JB-HF, is a galvanically isolated thyristor with a direct current trigger of 1 mA and an operating voltage of 15 Volts. It\'s designed to offer protection from transients in the voltage range of 5-180 Volts. In addition, its transient overvoltage withstand capability makes it an ideal component where robust protection from sudden transients is required. As such, the device is often used in car audio, AC-DC converters, and automotive electronics.

Working Principle

The working principle of the ATV15C180JB-HF is based on voltage suppression. Basically, it suppresses voltage fluctuations by examining the current voltage and then reverting the power supply back to normal when the voltage exceeds a certain level. The ATV15C180JB-HF has an on-chip threshold voltage detector so that the device can be triggered by transient overvoltage. The device acts like a mechanical switch that automatically detects and acts to prevent the overvoltage. The process works by slowly increasing a current at the gate of the transistor, until the threshold voltage of the device is exceeded. Once the threshold voltage is exceeded, the thyristor starts to conduct, mounting a short circuit between the p and the n terminals.
In this mode, the thyristor stops allowing current to pass through it, reducing the overvoltage to the level before it began. The current at the gate of the thyristor slowly reduces back to normal and the thyristor then returns to its non-conducting mode again. By quickly linking and unlinking the p and n terminals, the ATV15C180JB-HF is able to protect the device from any overvoltage. This process is done quickly enough to ensure no damage is done to the device.

Conclusion

The ATV15C180JB-HF is a special diode of the TVS family of components. It offers protection from transient overvoltage especially in sensitive automotive systems. The device uses an on-chip threshold voltage detector to detect any transients. The device quickly links and unlinks the p and n terminals to stop the overvoltage from damaging the device. This makes it suitable for protecting car audio, AC-DC converters, and automotive electronic systems.
