TVS - Thyristors

Thyristors (or Thyristor Voltage Suppressors) are an electronic device used to protect against large overvoltage transients. TVSs are solid-state switches with a gate terminal that is connected directly to the thyristor\'s cathode. When the gate terminal is reverse biased, the thyristor becomes conductive and can start to conduct current. This current then flows from the anode to the cathode and the thyristor becomes non-conductive again. TVSs are typically used to protect sensitive circuits from overvoltage transients resulting from electrical transmission line faults or sudden shifts in current.

The P3500ZC is a TVS device designed to protect against large overvoltage transients. This thyristor-based device is capable of withstanding inrush currents up to several thousand amperes, and is designed to protect power systems from surges resulting from line disturbances. It is available in both single and three phase models, with ratings ranging from 1,000 to 10,000 Amp peak pulsed current. The device can be mounted directly onto a printed circuit board, or in a separate enclosure.

The P3500ZC works by quickly clamping and dissipating the surge energy that is present when a high voltage transient occurs. The device comprises an area of high-resistance silicon-graphite material and a voltage dependent thyristor. When the voltage across the device reaches a certain level, the thyristor begins to conduct and the voltage across the device drops to a safe level. The energy is then dissipated by the silicon-graphite material, thus preventing the voltage from reaching damaging levels.

The P3500ZC is also designed to be highly reliable and durable. The device is designed to withstand multiple transient events, and features an integral reverse-polarity protection circuit, which allows it to survive in a reverse-voltage environment. Additionally, it can be operated in both harsh environments and high-temperature areas.

The P3500ZC is a versatile and reliable device that can be used in a variety of applications. It is well-suited for use in electric distribution systems, switchgear, and other high-voltage electric systems. It is also suitable for protecting sensitive electronic components and systems from destructive overvoltage surges.
