Thyristors - SCRs

The VS-12TTS08STRRPBF, also known as Silicon Controlled Rectifier (SCR) is a semiconductor device composed of four layers of alternating P-Type and N-Type materials. It is a selvage starting device intended to operate in adverse environments including high shock, vibration and temperature ratings. This type of SCR is designed to furnish high current applications such as controlling speed and torque of AC motors, phase angle control, resistive and inductive loads, lighting control and start-up applications.

Application Field

SCRs are used to control power in industrial, commercial and residential AC power applications. In addition, the VS-12TTS08STRRPBF can be used in a wide range of other applications such as controlling speed and torque of AC motors, phase angle control, resistive and inductive loads, lighting control and start-up applications.

Working Principle

The VS-12TTS08STRRPBF is triggered by the gate current passing through its gate terminal. Once the SCR is conducting, it will supply a continuous current for the applied load until the current decreases to the holding current. This holding current is the minimum amount of current required to keep the SCR conducting. When the gate control voltage is removed and the current passing through the SCR drops below the holding current, the SCR will turn-off.The VS-12TTS08STRRPBF also provides reverse blocking capability. This means that after the externally provided gate control voltage is removed and the current passing through the device falls below the specified holding current , the device will not be re-triggered after the anode-to-cathode voltage is reversed.

Conclusion

The VS-12TTS08STRRPBF can be used in a wide variety of AC power applications. It is designed to provide reliable and robust operation, even in adverse environmental conditions. This device is capable of providing reverse blocking capability during its operation which helps ensure safe operation. Furthermore, this device can easily be controlled by providing an externally provided gate control voltage. All of these features make the VS-12TTS08STRRPBF an ideal choice for AC power applications.
