RI Thyristor IRKT106/22Overview

The IRKT106/22 is a high‑power thyristor (SCR) module from the IRKT family (Thyristor‑Thyristor topology) made by IRI . It is designed for industrial applications requiring controlled rectification or phase control, such as DC power supplies, welding machines, battery chargers, motor drives, etc.

The “/22” suffix typically refers to the voltage rating class (e.g. 2200 V) in many thyristor modules. “106” refers to its current class (in this series likely around 105 A average). The IRKT106 is part of IRKT Family, which has modules in the current range ~100‑240 A and voltage up to 2200 V.  

Expected Key Specifications (Typical / Approximate)

Features & Benefits

• High voltage capability (≈ 2.2 kV) makes it suitable for medium to high voltage DC applications.

• Good average current handling (≈100‑110 A) coupled with decent surge capability means it can handle both steady loads and temporary peaks.

• Dual thyristor topology ensures redundancy or flexibility in circuit arrangements.

• Rugged packaging, designed for industrial duty, with temperature range, mounting style suitable for heatsinks.

• Moderate gate drive requirement (low voltage, modest current) simplifies gate driver design.

Applications

• Controlled DC power supplies / rectifiers (for example for electroplating, battery charging).

• Welding rectifiers or industrial welders.

• Motor drives / soft start units.

• Inverters or circuits which need phase control.

• Renewable energy or heavy industrial equipment requiring robust SCR modules.

Caveats / Important Design Considerations

 

• Adequate cooling / heatsinking is essential, especially at high current or elevated ambient temperatures.

• Surge current ratings are for short durations; repeated or continuous surges will reduce life.

• Ensure that reverse or dv/dt protections are in place, as high voltage and sudden changes can trigger unwanted firing.

• Gate circuits must supply clean trigger pulses, since the threshold is low—noise or improper gating can cause misfiring.

• Check that the module's mounting and case (common anode/cathode) are compatible with your system for grounding and insulation.
