TVS - Thyristors provide protection to applications and networks by protecting them from voltage spikes caused by lightning, electrostatic discharge, and induced radio noise. The P3500SCRP, one of the leading TVS devices, offers fast response, low holding voltage, low leakage current, and advanced protection capabilities suitable for various applications. It has an advanced on-device ESD clamp and is capable of handling transients from 350V to 1500V.

The P3500SCRP features a bidirectional SCRP element and voltage limiter which makes it suitable for both alternating current and direct current applications. It can also handle huge surge voltages up to 35 A, 30 kA peak at 8/20 μs. The SCRP (silicon-controlled rectifier protection) element provides fast response, low turn-on voltage, and low leakage current services to allow its use in more applications. Additionally, it has an adjustable overvoltage protection level setting, making it suitable for various demands in different applications.

The P3500SCRP is commonly used in a wide range of applications, such as wireless communication modules, low/medium voltage power supplies, data communication circuit boards, automotive electronics, and many more. Its fast response time eliminates the damage caused by large transient current and gives the device an outstanding protection performance. It also offers a long operation life as it features an advanced temperature compensation firing mechanism against surge currents and reverse polarity voltages.

The working principle of the P3500SCRP can be divided into two parts. Firstly, the SCRP element provides the transfer characteristics with very fast switching times that allow the device to protect against large voltage transients. When the over-voltage threshold is exceeded, the device allows current to flow. Secondly, the voltage limiter reduces the voltage by providing shunt current. It helps limit the amount of voltage that can be caused by long-term over-voltage conditions.

Overall, TVS - Thyristors, like the P3500SCRP, provide fast response and reliable protection from transients and surges for various applications. Its advanced features, such as an adjustable overvoltage protection level setting, temperature compensation firing mechanism, and bidirectional SCRP element make it suitable for a number of applications.
