Thyristors are a semiconductor family of switches that have three-way connections, also known as a four-layer diode. They are widely used in electronics, computers and communications equipment as power control elements. Thyristors- SCRs, specifically SK035KTP, are ideal for AC and DC power control applications in industrial, commercial, HVAC and IoT (Internet of Things) projects.

SK035KTP is a thyristor-type AC/DC power switch with a sensitive gate trigger current (the trigger voltage when loaded is 0.8V or less) that is suitable for inrush current limiting and for controlling small to medium motors. It has an operating temperature range of -20°C to 80°C, a maximum PIV voltage of 600V and a maximum on-state current of 65A.

For the application field of SK035KTP, it is usually used in motor control, light control, inrush current limiting and over current protection due to its high sensitivity, fast response time and high operating temperature. It is suitable for both AC and DC applications, such as switching lighting circuits, controlling door open/close systems, variable speed motor drives and controlling pumps.

The SK035KTP normally blocks the current until it is triggered. It is triggered by a small current which is sourced by a trigger circuit, usually a triac or transistor. Once the trigger circuit has been activated, the positive half-cycle of the AC voltage or the full DC voltage applies across the SCR, allowing the current to pass from anode to cathode. Its gated SCR structure eliminates the need for an external turn-off voltage for switching in higher voltage applications, making it a cost-effective solution for a wide range of applications where AC and DC power supply are present.

The main working principle of SK035KTP is that it uses a small current to pass through the gate, thus triggering the main current. When the gate is on, the device turns on and current flows from anode to cathode, allowing power to come through. When the gate is off, no current is allowed to pass and it remains in a blockade position, thus preventing any power being switched on or off.

In conclusion, SK035KTP is an ideal power control solution for various AC and DC applications due to its sensitive gate trigger current, fast response time and wide operating temperature range. It works by sourcing a small current through the gate, triggering the main current and allows power to pass from anode to cathode when the gate is on. The wide application field of SK035KTP allows it to be used in motor control, light control, inrush current limiting and over current protection projects.
