IRKT26/06A

Thyristors and Silicon Controlled Rectifiers (SCRs) are semiconductor devices that can be used as switching components. By managing the amount of current that flows through them, they allow for the effective control and modulation of electrical signals. In the case of more powerful circuits, the use of discrete SCRs or thyristors is not sufficient, and modular devices are needed.The IRKT26/06A is an SCR module made by Infineon Technologies that is used in an array of applications. It is suited to applications that require higher levels of power and voltage, and is used in motor control, power supplies, and other switch mode applications.

The IRKT26/06A Electrical Characteristics

The IRKT26/06A is an SCR module with a maximum current rating of 20A and a peak repetitive off-state current of 3000A. It is a 3-pin SCR module, containing two Thyristor junctions, a gate and a cathode. It has a control voltage of 2.5 to 8V, an off-state voltage of 500V, and a peak repetitive on-state current of 26A. The on-state voltage is 189V, a recovery time of 40μs and a temperature coefficient of -0.9mA/K.

The IRKT26/06A Applications

The IRKT26/06A is primarily used in motor control, such as in electric vehicles and home appliances, as well as in power supplies. This SCR module is ideal for motor control applications due to its high maximum current rating, low off-state voltage, and recover time. By using the IRKT26/06A module, the frequency and voltage of an electrical signal can be accurately controlled, allowing the electronic components of a circuit to be regularly and efficiently powered.

The IRKT26/06A Working Principle

The IRKT26/06A works by relying on the principle of bi-polar junction transistors (BJTs). When a current is applied to the gate, it triggers a chain reaction that turns on the SCR. This causes a current to flow from the anode to the cathode. When the current reaches a certain amount, the SCR turns off. This process can be repeated quickly by adjusting the current applied to the gate, allowing for precise control over a circuit.

Conclusion

The IRKT26/06A is an SCR module that is used in a variety of motor control, power supply, and other switch mode applications. It has an impressive current rating of 20A and a peak off-state current of 3000A. It works by using bi-polar junction transistors and its on/off status is regulated by controlling the current applied to the gate. By manipulating the timing and power of its current flow, it can be used as a switch to control circuits.
