TVS (transient voltage suppressors) diodes, also known as surge protection devices, are designed to protect electronic equipment from destructive voltage spikes. The PUSB3FR4Z TVS diode is an example of a specialized device designed to protect against high-voltage transients and provide superior protection for financial and industrial systems.

The PUSB3FR4Z is a bidirectional bidirectional TVS diode with a maximum peak pulse power of 3.5 kW. It features an integrated reverse avalanche diode and a wide range of reverse clamp voltages to suit a variety of applications. Additionally, its three layers of internal protection enable it to effectively prevent overvoltage, ESD, and spike transients.

The PUSB3FR4Z design is based on the proven Very Low Junction Capacitance (VLJC) technology. This technology allows the diode to maintain a low reverse current leakage, preventing power loss and preventing damage to the equipment from potentially harmful high-voltage transients.

The PUSB3FR4Z is well suited for a variety of applications, including data centers, financial systems, and industrial equipment. It is designed for high voltage overshoot protection and EMC (electromagnetic compatibility) in particularly sensitive applications. Additionally, it can be used in both series and parallel configurations depending on the needs of the application.

In terms of its working principle, the PUSB3FR4Z uses a number of techniques to protect against high-voltage transients. At its core is a reverse-biased Schottky barrier. This protects against higher voltage levels and provides superior protection compared to other TVS technologies.

The diode is also able to limit large surges and spikes in current by providing an impedance that is highly nonlinear to current flow. The diode is designed to absorb and dissipate the energy created from these transients, preventing them from reaching the equipment. This is known as "clamping," and it works by preventing the voltage from exceeding the maximum rating specified on the device.

Finally, the PUSB3FR4Z has a built-in reverse avalanche diode which provides additional protection. This diode works by shunting any transient currents away from the protected circuits, ensuring that the voltage spikes do not cause any damage to the system.

Overall, the PUSB3FR4Z is an effective and reliable TVS diode designed to protect sensitive electronic equipment against overvoltages and ESD surges. Its integration of reverse avalanche and VLJC technologies ensures that it can provide superior protection from both transients and EMC. Its wide range of reverse clamp voltages and series/parallel configurations make it highly versatile, and its ability to provide clamping and reverse current leakage protection makes it the ideal choice for a variety of applications.
