Thyristors are semiconductor devices that have three terminals, either DC or AC current. The three terminals are the anode (A), cathode (K) and gate (G). SCRs, or Silicon Controlled Rectifiers, are a kind of thyristor that has an additional gate terminal. When an SCR is triggered at its gate, it will allow current to pass from the anode to the cathode.

The S2065JTP is a type of SCR thyristor, specifically designed for power supplies and converters. It supports up to 65A (Average Current) at up to 600V in blocking voltage. A number of protection features are also included, such as short-circuit and overvoltage protection. It is also designed to withstand high-surge current while operating in temperature ranges from -40°C to +125°C. The S2065JTP is commonly used in adjustable speed drives, solar inverters and industrial motor control.

The working principle behind this thyristor is that when an electric current passes through the anode and the cathode, it triggers a spark, which turns the thyristor on. When the current is turned off, the thyristor remains on as long as there is a steady current passing through it. This ability to stay on or “latch” even when the applied current is removed is one of the main advantages of using SCRs for power supplies and converters.

The gate is used to control the current flow in or out of the device. When the gate is forward biased, a pulse of current is induced which sets the thyristor into a high-current “on” state. To release the thyristor from this state, the gate is reversed biased, removing the forward bias, which turns the thyristor “off” and the current stops. The gate and anode currents combine to form the gate control current, and it is this current which determines the polarity and control of the thyristor.

In summary, the S2065JTP is a type of thyristor that is designed for power supplies and converters, with a number of protection features. It utilizes a forward-biased gate current to turn the thyristor “on” or “off”, and it is able to “latch” even when the applied current is removed, making the S2065JTP a great choice for applications where power is being controlled and managed.
