The ATV30C430JB-HF is a Transil (Transient Voltage Suppressor) designed to protect electronic circuits in various conditions. It belongs to a class of TVS (Transient Voltage Suppressor) - Diodes. It primarily works by clamping down the voltage which it\'s protecting and thus isolating the chain of the circuit.

Application Field

ATV30C430JB-HF can be used in several different areas. It can protect equipment from high-voltage spikes in switching power supplies, protecting up to 5,000 watts with its maximum pulse power capacity. This TVS-diode can also be used in high-power industrial electronics, switching-mode power supplies in computer monitors or LCDs, mobile devices, microprocessors, inverters and many other applications.

In spite of its small size, ATV30C430JB-HF has enough power to protect high-power systems. With its ability to handle up to 1,500 volts, it can provide reliable protection even in extreme voltage conditions. It can also protect sensitive components from voltage and current spikes in the power line, preventing them from shorting or being damaged.

Working Principle

A typical Transil (TVS - Diode) such as ATV30C430JB-HF is made up of two parts. The first part is a diode with a breakdown voltage that is typically formed from a two-layer structure. This diode has the ability to conduct from anode to cathode, but only at a certain voltage value. The second part of the TVS-Diode is a voltage-limiting device, which contains a MOSFET (Metal Oxide Semiconductor Field-Effect Transistor). This device limits the voltage and current spike to protect the connected load.

When the voltage reaches the breakdown voltage of the diode, current starts to flow. This causes a rapid increase in current in the TVS, raising the voltage quickly and limiting the peak incoming voltage. The current is then redirected to the MOSFET, which acts as a resistor to further reduce the voltage and clamp the voltage spike. This action will limit the peak voltage of the inverter and protect it from overvoltage conditions.

By diverting the current away from the sensitive elements and limiting the peak voltage, the TVS-Diode helps to protect the inverter from destabilizing and damaging voltage and current surges. The MOSFET also helps to protect the connected components from damage as it limits the amount of current that goes to them.

The ATV30C430JB-HF is designed to protect systems under extreme conditions. It is reduced in size, but is still capable of handling up to 5,000 watts, with a peak pulse power capacity of 1,500 volts. This diode helps to protect electronic equipment from high-voltage spikes, as well as short-term current spikes. With its capabilities and compact design, the ATV30C430JB-HF provides effective protection in a variety of applications.
