K0900E70RP2

Thyristors - DIACs, SIDACs

K0900E70RP2 is an electronic component that belongs to the Thyristors family. It is part of the DIACs and SIDACs subcategory, thyristors that are used as an electronic switch to control the current flow in a circuit. This component can be used in either AC or DC circuits and provides an effective way to switch narrow pulses.

Application Fields

K0900E70RP2 components are used in various fields of electronics. Some common applications are in home appliances such as washing machines, refrigerators and ovens that have parts that need frequent switching. To ensure the safety of the user, these electronic products require a reliable switching device. Also, these thyristors are used in automotive electronics, LED lighting systems, emergency lighting systems, and systems that require precise control of current or voltage, such as measuring and control systems.

Working Principle

K0900E70RP2 thyristors are bistable switches, meaning they can maintain their current state due to the charge stored in their junction layer. This type of thyristor consists of two terminals (anode and cathode) and two junctions (a diode and a switch). The two junctions are separated by several layers and are filled with semiconductor material. This construction provides the bistable effect - the thyristor can maintain its current state for as long as a sufficient amount of current is passed through its junctions.

The working principle of DIACs and SIDACs is based on the electrical breakdown concept. By increasing the voltage across the junctions, electrons can be forced to jump and current flow is established. This process also causes a reverse voltage that reinforces the effect. The bias current in DIACs and SIDACs determines the exact voltage at which the switch is closed and the current is allowed to flow.

K0900E70RP2 is an example of a DIAC-SIDAC thyristor, meaning it combines the features of both types of devices. This type of thyristor can be used in AC and DC circuits, and provides a reliable switching solution for narrow pulses. When properly connected, this type of system yields a stable and capable control of current or voltage.
