Thyristors - SCRs, sometimes known as Silicon Controlled Rectifiers, are semiconductor devices that are widely used within the high-voltage electronics industry for switching and protective functions. Inverters, converters, motor controls, and high-voltage power supplies all utilize SCRs for fast and accurate switching. The S2070W81TP is an example of a modern SCR, and is widely used within industrial and military applications.The S2070W81TP is a 4-terminal, hermetically sealed SCR, and is specifically designed for use in high-voltage AC mission-critical applications. It is equipped with a high-voltage anode, cathode, gate, and control gate connections, and is capable of withstanding currents of up to 0.8A. The S2070W81TP also has an impressive surge capability, enabling it to handle momentary surges of up to 1.5A at 500V.The S2070W81TP is designed for AC mission critical applications due to its ability to monitor and control current and voltage levels in a variety of conditions. It is typically used in high-voltage power supplies, such as those found in the aerospace, automotive, and defense industries. This allows the safe and reliable operation of sensitive and expensive electronic components, preventing them from being exposed to damaging currents and voltages.The S2070W81TP works on the principle of a diode and a thyristor, making it a bidirectional switch. When the forward voltage on the anode is greater than the cathode voltage, the diode turns on, allowing current to flow. When the opposite polarity is applied, the diode is reversed, blocking current in both directions.The key feature of the S2070W81TP is its ability to control the current, allowing it to be used in a number of different industrial applications. With the addition of an external gate signal, it is possible to control the current flow between the anode and cathode terminals. This enables the SCR to be used in highly accurate, repetitive switching applications, such as motor controls and power supplies.In addition to its control functions, the S2070W81TP also provides a number of protective features to ensure the safe and reliable operation of the device. It also has an internal inverse current protection circuit, which prevents damage to the SCR in the event of an over-current or excessive voltage. This feature allows the S2070W81TP to operate reliably and safely in high voltage, high current applications.The S2070W81TP is an example of a modern day SCR, which is used in many high-voltage AC mission critical applications. It provides reliable and accurate switching, as well as the ability to control current, making it a valuable tool for industrial applications. It also features a number of protective features, ensuring that it remains safe and reliable for many years to come.
