TVS (transient voltage suppression) diodes provide surge protection for electrical systems. The BZG04-18TR3 is a device capable of handling high current spikes with quick response time and low leg voltage, making it an ideal choice for protecting critical systems during a surge.

The BZG04-18TR3 is designed with low capacitance and high maximum peak pulse power. It ensures the highest levels of protection for sensitive electronics with high-speed response and maximum protection from strong transients and snubber circuits. The built-in ESD protection means that the device is designed to guard against sudden fluctuations in voltage that could otherwise damage systems and components.

The main applications of BZG04-18TR3 are automotive, consumer, industrial and telecom systems. It finds use in a wide range of equipment from automotive ECUs to surge protected UPS. The travelling wave suppression technology used in this device makes it suitable for high frequency, high power applications.

The working principle behind the BZG04-18TR3 is the use of a low capacitance, fast responding TVS diode to absorb high voltage transients. The device works on the principle of a reverse breakdown voltage, where an electric current can exceed the specified value and the voltage between the anode and cathode of the diode drops to a predetermined value (called the ‘clamping voltage’). Once the voltage reaches the ‘clamping voltage’, the BZG04-18TR3 acts as a clamp, preventing further voltage surges.

The internal structure of the device consists of a number of components that work together. The main components are the transient voltage suppression diode, a resistive element and a bypass capacitor. When a voltage surge occurs, theTVS diode conducts current and the resistor limits the current flowing through the diode. The bypass capacitor helps filter out RF signals and noise that could interfere with the operation of theTVS diode. Thus it ensures perfect protection of the system or equipment in case of a voltage surge.

In conclusion, the BZG04-18TR3 is a highly efficient and reliable TVS diode. It offers superior protection against voltage surges in electrical systems in a wide range of applications. It has a quick response time, low leg voltage and high peak maximum pulse power. Its low capacitance makes it the ideal device for high frequency, high power applications. Moreover, its internal components work together to provide reliable protection.
