Thyristors, specifically Silicon Controlled Rectifiers (SCRs), are devices that consist of three or four closely spaced p-n junctions. When connected to an external power source, they provide a mechanism that can switch large currents in either an opened or a closed state. In particular, the S2070W82 SCR is designed with thermal protection, overvoltage and overcurrent features that make it suitable for use in many applications.

Application Field

The S2070W82 is a robust, general purpose SCR developed to engineer a wide range of power control applications. It can be used to control and switch high power loads such as relays, solenoids, motors, and other load devices. It can also be used in harsh environments where its excellent surge and pulse current handling capabilities offer added protection for the system. Furthermore, it is ideal for use in industrial equipment, consumer electronics, and automotive applications.

Working Principle

The S2070W82 operates by controlling the flow of current through SCR switches in either open or closed states. When the SCR is in an open state, the current flowing through it is zero; when the SCR is in a closed state, the current flowing through it is maximized. This dual-state operation can be useful for several control applications such as pulse width modulation (PWM), phase-angle control, load shedding, and soft start.

The unique feature of the S2070W82 is its on-state voltage drop, which is significantly lower than other devices. This low drop is achieved by using an advanced doping technique, which allows for improved electrical speed and reduced losses. Additionally, the device is designed with a low-power threshold voltage, which allows for easy switching without any external gate bias. It further adds to the device\'s versatility and makes it ideal for usage in industrial applications.

The S2070W82 utilizes silicon avalanche technology, which is beneficial in terms of improved efficiency and reliability. Its built-in thermal protection provides the device with additional safety measures, meaning that it can be used in most harsh environments without the worry of overheating or overloads. Additionally, the device comes with a wide range of features that make it an attractive choice for many applications.
