SCRs: S6006VS3TP application field and working principle

Sensitive SCRs, like the S6006VS3TP from STMicroelectronics, are three-terminal semiconductor silicon devices that are designed to control and switch big power. SCRs are electronically and magnetically triggered, electronic switches that can be controlled with a single power signal. The S6006VS3TP, specifically, is a robust, low-saturation, sensitive SCRs that feature a variety and high power capability hermetic package.

Applications of S6006VS3TP

The S6006VS3TP are sensitive SCRs, meaning they are are promptly triggered with small current and low gate power. This makes them an excellent choice for use in power conversion applications, especially AC and DC motor controls, as well as lamp and heating regulators. In many of these uses, the S6006VS3TP can help reduce power losses, improving the overall efficiency of the device or equipment. The hermetic package of the S6006VS3TP allows for a high level of reliability and robustness that makes it suitable for various applications involving extreme environmental conditions.

Working Principle

The operation of the S6006VS3TP - and all SCRs - follows the basic principles of triggering and latching. When a minimum current is passed through a gate, an avalanche of electrons is triggered and emited through the anode-cathode junction. As a result, a large unidirectional voltage drop will open across the switch and current will start to flow through the junction. At this point, the SCR is said to be in "on" state, and its internal characteristics are such that it will remain in that state until the drive current is removed and not internal electronics can reset it to its "off" state.

In general, the sensitive SCRs like S6006VS3TP are triggered with less gate power than their standard equivalents, allowing for more feasible applications with lower costs and higher efficiency. Ready-to-use SCRs like the S6006VS3TP also make for an easier installation and use.

Summary

The S6006VS3TP is a sensitive SCR from STMicroelectronics that is designed for high power application. It is suitable for AC and DC motor control, as well as other applications involving power conversion or extreme environmental conditions. It is triggered with smaller currents and lower gate power than other SCRs, allowing for more cost-effective installations. The working principle of the S6006VS3TP is equivalent to any SCR, in that it is triggered when a minimum current is passed through a gate, generating an current flow that continues until the gate current is removed.
