IRKH26/16A

Thyristors are semiconductor devices with multiple terminals for controlling electric current flow. Thyristors are mainly divided into two types: thryistors with three terminals and thyristors with four terminals. A thyristor with three terminals is called a SCR (silicon controlled rectifier), and one with four terminals is called an SCR module. The IRKH26/16A is an SCR module produced by Infineon. It is suitable for high voltage and high current applications.

The IRKH26/16A has four terminals, namely gate, anode, cathode and gate driver. The gate is a voltage-controlled terminal, and it is used to control the firing of SCR. The anode and cathode terminals are both current-carrying terminals used to conduct current between them. The gate driver terminal is used to supply the gate voltage when the SCR is fired.

The IRKH26/16A is widely used in power supplies, inrush current limiters, rectifier bridges, DC motor controller and so on. It can be used for high-voltage and high-current applications and can be used for solid-state relays. To prevent unwanted firing of SCR, a gate resistor can be connected between the gate and the gate driver terminals.

The working principle of the IRKH26/16A is simple. When a voltage is applied to the gate, the metal-oxide semiconductor field-effect transistor (MOSFET) switches on, which triggers the SCR. This causes current to flow through the anode and cathode terminals. The amount of current flow depends on the voltage applied to the gate. It can be increased or decreased by changing the voltage. When the SCR is fired, a current path is established between the anode and the cathode, thus allowing current to flow through it.

The IRKH26/16A module has several advantages over other SCRs. It has a low driver power requirement, a low on-state voltage drop and a low gate current. Its reverse recovery time is also shorter than that of other types of SCR. This makes it ideal for high-power applications, such as motor controls and inrush current limiters.

In conclusion, the IRKH26/16A SCR module is a versatile device that is widely used in power supplies and other high-power applications. It is easy to use and can handle high voltages and currents. It has a low on-state voltage drop and a low gate current requirement, which makes it ideal for these applications. Furthermore, its reverse recovery time is shorter than that of other types of SCR.
