Transient Voltage Suppressor (TVS) diodes are special electronic components that are designed to protect vulnerable electronic circuits from destructive voltage transients, such as electrical surges and spikes. In this article, we will discuss the application field and the working principle of the ATV15C120JB-HF diode, a popular TVS diode that is widely used in automotive and industrial electronic systems.

The ATV15C120JB-HF diode is a three-terminal uni-directional TVS diode that is designed to protect automotive and industrial electronic systems from voltage transients. This diode features a low reverse leakage current, low leakage voltage, and a low capacitance. Its operating voltage range is from -5V to +18V, and its clamping voltage is usually 30V. It is usually available in surface mount and axial lead packages, and it is capable of handling up to 15A currents.

The ATV15C120JB-HF diode is commonly used in automotive and industrial electronic systems where electromagnetic interference (EMI) must be protected. These systems can include automobiles, industrial control systems, alarms, UPS systems, and circuit boards. This diode is also capable of protecting a variety of sensitive electrical circuits, such as audio circuits, video circuits, and data communications circuits.

When the ATV15C120JB-HF diode is used in an electronic system, it is typically connected between a power source and a sensitive electronic component, such as a transistor or an integrated circuit. The diode acts as a “shunt”, creating a low-resistance path for voltage transients and preventing them from damaging the sensitive component.

The way in which the ATV15C120JB-HF diode works is based on the principle of avalanche breakdown. When an electrical surge exceeds the diode’s breakdown voltage, it causes the diode to break down electrically, resulting in a large increase in current flow. This large current flow creates a low-resistance path which diverts the surge away from the sensitive component.

The ATV15C120JB-HF diode provides superior performance when compared to other types of transient voltage suppressors. Its low capacitance helps to minimize noise in sensitive electrical circuits, and its low leakage current helps to reduce power losses in automotive and industrial applications.

In conclusion, the ATV15C120JB-HF diode is a versatile and reliable transient voltage suppressor that is ideal for protecting sensitive electronic systems from destructive voltage transients. Its low capacitance, low leakage current, and high-current ratings make it the perfect choice for automotive and industrial electronic designs.
