The IRKH136/12 is a thyristor module for 12-pulse applications. Designed for both medium and high power applications, it offers high current regulation, fast rise times and low leakage current. It is designed for use in a variety of industries including industrial motor drives, generator protection and commercial lighting.

The IRKH136/12 thyristor is part of the SCR family of components, meaning that it is a semiconductor switch controlled by a current or voltage source. This type of switch offers high power management capabilities and a variety of other benefits. It can be used in a broad range of applications including switched-mode power supplies, home appliance controls, energy metering, and renewable energy systems. SCRs are especially suited for applications where high switching speed is desired due to their ability to operate in a linear manner.

The IRKH136/12 module has a wide range of capabilities, including fast rise times, low leakage current, and high current regulation. It can handle up to 1500 VDC and has an overvoltage protection of up to 2.2 kV. The module also features resistor controlled turnon, rugged construction for robustness, and diode reverse commutation for higher power applications.

The working principle of the IRKH136/12 module relies on applying a voltage or current to the gate terminal. This triggers a conduction from the anode to the cathode leading to the device being in the forward-blocking mode (i.e. the switch is open). When the voltage or current is removed, the device is switched off, thus becoming reverse-blocking.

Another important feature of the IKH136/12 is its ability to provide an adjustable turn-on time. This is achieved by a variable gate resistance which is adjusted by a resistor connected across the gate and the cathode. By changing the resistance value, the turn-on time is adjusted accordingly, to match the specific application requirements.

In conclusion, the IRKH136/12 thyristor module is a reliable and high-performance device for 12-pulse applications. Its adjustable turn-on time, fast rise times and low leakage current make it an excellent choice for industrial motor drives, generator protection and commercial lighting applications.
