T707023364BY Datasheet/PDFThyristors - SCRs (silicon-controlled rectifiers) are four-layer semiconductor devices that are used as switches and in various control and power circuits. The device is composed of two or more PN or N regions, which when forward biased form four layers. The two outer layers form the anode, while the two inner layers form the cathode. When the SCR is triggered into conduction, it becomes a short-circuit from anode to cathode. This "on-state" is called the "ON" state and occurs when a sufficient triggering current is applied to the SCR.
The T707023364BY is a DC-rated, four-layer silicon-controlled rectifier (SCR) with built-in enhanced dynamic integrity. Designed to meet both ANSI and UL ratings, this silicon control rectifier is offered in a variety of voltage and current ratings and can be used in numerous applications, including lighting controls, power supplies, and motor control.
In terms of applications, T707023364BY is ideal for use in a variety of DC rectification applications, where high-speed switching and low on-state voltage drop can increase the efficiency of the circuit. Additionally, the device offers improved trigger current, for enhanced light control, as well as low gate leakage for increased reliability. Furthermore, this SCR is capable of interrupting large resistance welding currents and is capable of withstanding substantial levels of surge current.
The T707023364BY SCR works according to the same basic principle as other SCRs - when a sufficient triggering current is applied to the gate, the SCR switches from an "OFF" state to an "ON" state, allowing current to pass from the anode to the cathode of the device. Once the "ON" state is achieved, current can flow both ways between the anode and cathode, allowing the device to remain in an "ON" state even after the triggering current has been removed. Finally, the device switches to an "OFF" state when the anode-cathode current drops below a certain threshold.
All in all, the T707023364BY is an ideal choice for use in DC rectification applications, where its low on-state voltage drop and improved trigger current can increase the efficiency of the circuit. Additionally, the device offers enhanced dynamic integrity and excellent surge current withstand, making it a perfect choice for applications requiring high-speed switching, such as lighting controls, power supplies, and motor control.
