RIR Power Electronics Secures First Overseas Order for 125mm 5kV SCR Thyristors
Mumbai, May 27, 2026: RIR Power Electronics Limited, a Mumbai-based manufacturer of high-performance semiconductor devices, assemblies, and energy management systems, has secured its first international order for 120 units of its advanced 125mm 5kV Silicon-Controlled Rectifier (SCR) thyristors.
The order marks a significant milestone for the company and reinforces growing global confidence in RIR Power Electronics’ portfolio of high-power press-pack thyristors known for innovation, reliability, and energy efficiency.
The 125mm 5kV SCR thyristors are specially engineered high-current semiconductor switching devices capable of handling extremely high peak currents and high di/dt pulses over short durations. Built using a 125mm silicon chip enclosed in a robust press-pack structure, these thyristors offer superior mechanical reliability and optimized lifetime control, making them ideal for demanding heavy-power applications requiring exceptional current handling capability and operational reliability.
The order has been placed by a leading Class I Electrical EPC contractor engaged in turnkey electrification projects for industries and power plants globally. The development further strengthens RIR Power Electronics’ positioning as India’s leading vertically integrated Silicon Carbide (SiC) semiconductor manufacturer.
Commenting on the development, N. Ramesh Kumar, Managing Director & CEO of RIR Power Electronics Limited, said: “We are delighted to announce the order win from Overseas Customer for 120 units of our advanced 5kV SCR thyristors; making it one of the largest single order for our range of 125mm pulse power thyristors. While order execution is slated for completion by end of 2026, we are hopeful of expanding this mandate and strengthening our partnership with many such Class I Electrical EPC Contractors over the foreseeable future.”
He adds, “With over five decades of rich expertise in the power electronics space, RIR Power Electronics is scripting a bold new chapter with the vision of powering India’s progress through the company’s range of semiconductor solutions. Towards this end and recognizing the importance of SiC semiconductors as building blocks of India’s high-power future, the company is also setting up a state-of-the-art SiC semiconductor manufacturing plant in Odisha; a significant milestone in advancing India’s semiconductor industry and strengthening domestic manufacturing capabilities.”
RIR Power Electronics’ range of high-power large-area press-pack thyristors are designed for a range of applications such as HVDC transmission valves, Static VAR Compensators (SVC), medium-voltage soft starters, high-power rectifiers, crowbar protection systems, pulsed capacitor discharge systems, high-power rectifiers, traction & legacy locomotive systems as well as in several defense systems where huge energy bursts are required in extremely short time durations. The company is anticipating stronger business momentum in the upcoming quarters as it focuses on broadening its product portfolio while also expanding its global presence in the power semiconductor industry.
