Thyristors are defined as a group of three-terminal semiconductor devices and are primarily used to regulate the flow of electrical current in a variety of commercial electronic applications.

K2400SHRP is one of the leading thyristor families that offer increased speed and efficiency while still providing reliable operation and controlling the flow of current quickly and efficiently. K2400SHRP is a four-layer thyristor specifically designed for solid-state switching in power applications such as AC->DC, DC->AC and DC/AC bridge rectifiers. This device offers advantages over traditional four-layer devices in that it provides high surge current capability, low input trigger current and low dynamic on-state resistance.

The main application fields of the K2400SHRP thyristors are switch mode power supplies, motor drives, UPS systems, AC inverters and adjustable speed drives. These thyristors find usage in a wide range of industries, from automotive to medical and military applications. Furthermore, they are also increasingly being used in renewable energy solutions, such as solar inverters and wind turbines.

K2400SHRP thyristors can operate in two different switching modes depending on the current flow: static mode, where a reverse-biased gate current is applied to turn the device off after it is initially turned on; and dynamic mode, where the reverse-biased gate current is always present and the device is never turned off.

The working principle of the K2400SHRP thyristors is based on a rectifying diode, and it functions just like a bipolar transistor. All thyristors consist of two PN junctions connected in series, one acting as the forward biased diode and the other acting as the reverse biased diode. When the anode of the forward biased diode is forward biased, current flows through the device and the thyristor is in the on-state. When the reverse biased gate current is turned on, the thyristor returns to its off-state. When the gate current is applied in a certain polarity, the thyristor switches off instantly.

Another type of thyristor is the DIAC, which stands for “DIode ACtor”. DIACs also uses the same basic principles as thyristors but differ in their operation. DIACs are specifically designed for low voltage applications such as AC power supplies and are used to control the threshold voltage or trigger point at which the thyristor switches on or off. With DIACs, the switch-on and switch-off current are usually lower than those of a thyristor, making them well suited for applications needing precise control of the start-up and over-current protection.

SIDACs (Synchronous Interrupt Diode ACtors) are another type of thyristor that are used in applications where the turn-on speed of the thyristor is of utmost importance. The SIDAC has a highly symmetrical turn-on characteristic and the switch-on time is much faster than the turn-on time of a diac. The SIDAC can also be used as a rectifier.

The K2400SHRP thyristors family provides higher switching speeds, increased efficiency and precise control of current compared to conventional devices. The K2400SHRP devices provide higher surge current capabilities, lower input trigger current, low dynamic on-state resistance, and are widely used for many power applications. DIACs and SIDACs are widely used in AC applications and provide precise control of the starting voltage and fast turn-on times.
