IRKH71/16A is a member of a wider family of semiconductor-based electronic components and devices referred to as Thyristors. These components are also known by other names such as silicon-controlled rectifiers (SCRs) or rectifier-controlled switches (RCS). IRKH71/16A is a specialized type of Thyristor known as a module.

Thyristors are electronic switches that act as rectifiers and voltage- or current-sensitive switches. They are composed of either two or four diodes in parallel with a single gate that can be used to control the flow of current. The terms “Thyristor” and “SCR” are generally used interchangeably, though the term “Thyristor” is typically used to refer to components with four or more rectifiers. IRKH71/16A is an example of a four-rectifier type of Thyristor.

Thyristors are used in applications such as power control, AC-DC and DC-DC conversion, static switching, and overvoltage protection. In power control applications, Thyristors are used as controlled switches for controlling the flow of power to a load. They can also be used as rectifiers for converting alternating current (AC) power to DC power. In static switching applications, Thyristors can be used for non-contact switching of high-voltage AC signals.

IRKH71/16A is designed for use in high-voltage and high-current applications. It features a reverse blocking voltage rating of up to 1600 V, a forward on-state current rating of up to 16 A, and a peak on-state current rating of up to 40 A. It is constructed from a silicon substrate and utilizes two N-channel MOSFETs, two P-channel MOSFETs, two 2x2x2 diodes, and two short-circuit current limiters. Its gate is driven by a built-in gate driver.

The working principle of IRKH71/16A is based on the concept of gate triggering. When a gate voltage is applied to the module\'s gate lead, the Thyristor switches from an off-state to an on-state by allowing current to flow from the anode to the cathode. The on-state characteristics of the module depend on the gate voltage, the load voltage, and the load current. When the gate voltage is removed, the Thyristor switches back to its off-state.

In summary, the IRKH71/16A is a specialized type of Thyristor module that is designed for high-voltage and high-current applications. It features a reverse blocking voltage rating of up to 1600 V, a forward on-state current rating of up to 16 A, and a peak on-state current rating of up to 40 A. The working principle of the module is based on the concept of gate triggering, in which a gate voltage is applied to the module\'s gate lead, causing the Thyristor to switch from an off-state to an on-state.
