Thyristors are an important part of TVS (Transient Voltage Suppressor) technology. The P1900RE is a state of the art transient voltage suppressor designed to protect sensitive electronic equipment from damage caused by power spikes and other transient voltage events. It is a three-terminal device, consisting of an anode, cathode and gate, and is available in both low- and high-voltage versions. The low-voltage version is used to protect electronic equipment operating below 30 volts, while the high-voltage version is used to protect electronics operating at or above 30 volts. This device is a combination of fast-action transient response time with low let- through voltage.

The P1900RE works by sensing transient voltage events, and then quickly responding to short-circuit the power supply so that the voltage remains below the destructive level. In order to do this, the P1900RE uses a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) as a current-controlled switch. When the P1900RE senses that the voltage at its terminals has exceeded a certain range, it turns on the MOSFET, which in turn causes the circuit to be grounded. This short-circuits the harmful voltage away from the sensitive electronic equipment, thus protecting it from damage.

The P1900RE is also designed to reduce the post surge voltage to a minimum level when the transient event has passed. It does this using a harmonic current-limiting circuit. This circuit senses and limits the current passing through the thyristor by limiting its voltage and then dissipating the excess energy as heat. This ensures that the voltage does not return to level above the desired level.

The P1900RE is suitable for a number of applications due to its wide range of operating voltages (30 to 1000 volts) and high peak pulse current ratings (7.5 to 8.5 kA). It is used in a range of different systems including telecommunications systems, power systems, industrial equipment, safety systems, and consumer appliances. It can also be used to protect sensitive medical equipment from voltage spikes.

Overall, the P1900RE is an ideal choice for protecting sensitive electronics from damage due to power surges and other transient voltage events. Its wide range of operating voltages and high peak current rating make it suitable for a range of different applications. Additionally, its current-limiting circuit ensures that the post surge voltage remains low after the transient event has passed. Thanks to its fast acting response times and low-let through voltage, the P1900RE is the perfect choice for protecting your sensitive electronic equipment.
