Thyristors - SCRs

A silicon controlled rectifier (SCR) is a four-layer semiconductor that switches over its anode automatically with an external or internal gate signal. These are used in power control and switching applications, where high power need to be controlled quickly and reconfigured quickly. The STT0019 is a type of SCR which has some special features that make it well suited for certain applications. It is designed for controlling up to 500kVA in three- or four-phase systems and is also presented in a compact form with a lead free/RoHS compliant termination style. The device has a soft turn-off technology that helps reduce conducting losses by allowing current flow on the reverse path. It also has a reverse blocking and very fast turn-off time, making it able to protect against surges and other accidents.The STT0019 SCR is available in a range of current ratings, ranging from 200A to 2500A in three-phase systems and up to 4000A in single-phase systems. It is compatible with various tools, components and systems and is capable of controlling multiple phases simultaneously. The STT0019 SCR is highly reliable and durable and can withstand temperatures of up to 150°C. It is designed to have a low turnoff time in the nanosecond range, making it suitable for high powered applications. It also has a high-speed turn-off time for lower power applications, making it suitable for applications such as uninterruptible power supplies (UPS). The STT0019 works on the principle of voltage-controlled switching between its anode and cathode. When the gate signal applied to its gate terminal is below the threshold level, the device remains off and no current flows. However, when the gate signal exceeds the threshold, the SCR switches on and current begins to flow through the anode-cathode junction. The switching is quick and reliable since the SCR can be turned on only when it receives a suitable gate signal in the required voltage.In summary, the STT0019 is a reliable and durable SCR that is used for power control and switching applications. It is available in a range of current ratings and offers a range of features and benefits. It has a low turn-off time and is compatible with various tools and components, making it suitable for various applications, especially those involving high power uninterruptible power supplies.
