Thyristors - SCRs
Thyristors are a type of semiconductor device, also known as a silicon controllable rectifier (SCR). In its simplest form, an SCR consists of two PN-junctions placed back-to-back, allowing current to flow in one direction only. This makes it an ideal device for controlling power, and a variety of applications, ranging from motor and lighting control, to AC power switching, which require precise timing of the gate pulses and tightly controlled current conduction.
The 2N690A is an SCR designed specifically for high-current applications. The SCR has three pins, labeled D, G and S, which each have distinct functions. D is the device anode, G is the gate and S is the device cathode. Attaching a voltage to the anode causes current to flow from the cathode to the anode, provided the gate is properly triggered. The gate must be of a higher voltage than the device anode in order to switch the device on and off, making it an ideal device for controlling power.
The most common application of the 2N690A is power switching and motor control. Its ability to switch large currents and operate at high voltages, makes it ideal for controlling high power components such as motors and light systems, typically found in industrial, automotive, and agricultural applications. The SCR can also be used in high power AC switching, allowing AC power to be interrupted and restarted with precise timing. It can also be used in a variety of other applications that require precise timing and power switching, such as solar battery charging, and electronic load regulation.
In addition to its high current capabilities, the 2N690A also has several advantages over other types of SCRs. It has a higher gate breakdown voltage than most SCRs, meaning it can switch larger current levels than conventional SCRs. It also has a higher peak inverse voltage rating than most SCRs, making it more suitable for high voltage applications. Finally, it has a built-in crowbar protection circuit, which helps protect the device from high current inrush.
Understanding the fundamental principles of operation and circuit functionality of the 2N690A SCR is critical for ensuring the correct application and correct usage of the device. The 2N690A application field and working principle is a critical part of any classroom or workshop instruction on SCR control. Understanding how the device works and how to properly use it within a variety of circuit designs will help ensure it is used properly in a wide range of applications.
