RIR Power Electronics Expands SiC Diode Manufacturing with Taiwan’s Pro Asia Semiconductor

RIR Power scales up global SiC diode production with Taiwanese fab partnership and prepares for domestic commercial ramp-up from its upcoming Odisha facility.

RIR Power Electronics Ltd., a pioneer in high-power semiconductor solutions listed on the Bombay Stock Exchange (BSE: 517035), has announced a major expansion of its 1200V Silicon Carbide (SiC) diode manufacturing through a strategic partnership with Pro Asia Semiconductor Corporation (PASC), Taiwan. The collaboration accelerates RIR’s production of SiC-based power devices and positions it to meet global dem
and in automotive, industrial, renewable energy, and defence markets.The move is expected to fast-track the company’s entry into advanced markets by introducing a portfolio of Schottky Barrier Diodes (SBDs) ranging from 2 amps to 60 amps. These products are already in shipment from Taiwan to customers in India, the United States, and other Southeast Asian markets.

RIR’s technology capabilities stem from an exclusive IP transfer deal signed in October 2024 with Sicamore Semi, USA. This agreement provides RIR with full rights to manufacture and commercialize SiC diodes, MOSFETs, and IGBTs developed for 4-inch wafers, now successfully scaled for 6-inch wafer production. The scale-up was supported by technical collaborators Vortex Semi (USA) and PASC (Taiwan).
According to Dr. Harshad Mehta, Chairman and Director of RIR Power, “This achievement marks a significant leap in our ability to serve global SiC demand. The shipment of 1200V diodes produced on 6-inch wafers from PASC paves the way for rapid commercialization from our proposed Odisha fab.”

Purchase orders have already been secured from Richardson Electronics (USA) and Ankit Plastics (India), further validating RIR’s market relevance in high-efficiency semiconductor technologies.
This expansion aligns with India’s Make in India vision. RIR’s upcoming ₹618 crore semiconductor fab in Odisha is expected to enhance India’s indigenous capability in semiconductor production, reduce dependency on imports for strategic applications, and contribute to employment generation.

RIR’s integrated strategy links global supply chain collaboration with domestic infrastructure development. The company aims to position itself as a vital player in India’s semiconductor ambitions by reinforcing reliability and access to critical components for the defence, energy, and transportation sectors.
