Engineered for Extreme Power
High-Performance Semiconductors for Critical Industrial Applications
THYREX Semiconductors delivers robust power solutions designed to operate reliably in the world's most demanding environments. Driving the systems that power modern infrastructure.
Ultimate Reliability
Hermetically sealed metal cases (Stud & Capsule) designed to withstand extreme heat, vibration, and thermal cycling.
High Power Density
Handling currents from 25A up to 6000A and voltages up to 4500V for efficient power conversion.
Seamless Replacement
Our components are engineered as direct "drop-in" replacements for discontinued parts from major global brands.
Mission-Critical Defense Systems
In the defense sector, failure is not an option. THYREX supplies high-reliability power semiconductors engineered to meet rigorous MIL-grade standards. Our components are the backbone of tactical energy systems, providing stable power conversion under the most hostile conditions, including extreme temperature variations and mechanical shock.
Our Fast Recovery Diodes and Pulse Power Thyristors are specifically optimized for high-frequency applications such as radar power supplies, electromagnetic launch systems, and avionics ground support units.
Driving the Future of Rail Transport
Modern railway electrification demands components that can handle massive power surges and continuous high-load operations. THYREX provides heavy-duty Phase Control Thyristors and Rectifier Diodes essential for traction substations and electric locomotive propulsion systems.
From high-speed trains to urban light rail and trams, our semiconductors ensure efficient energy transmission in Traction Inverters and Auxiliary Power Units (APUs). Our robust capsule (hockey-puk) designs offer superior thermal management, extending the lifecycle of critical infrastructure.
Powering Global Industries
Beyond defense and transportation, THYREX components are trusted in heavy industries worldwide. From the steel mills requiring Induction Heating precision to renewable energy projects needing efficient Inverters, we provide the reliability that keeps the world moving.
