TDK-Lambda i1R ORing MOSFET Modules

TDK-Lambda i1R ORing MOSFET Modules are High-efficiency and low-loss power devices designed to replace traditional diodes. These MOSFET modules utilize advanced MOSFET-based circuitry to minimize reverse-current transients and conduction losses, achieving up to 99.5% efficiency. The i1R ORing MOSFET modules address critical challenges in thermal management and power density, especially in high-current systems. These MOSFET modules provide a compact, shielded form factor that supports up to 80A output current with minimal derating, enabling reliable performance in space-constrained environments. The i1R MOSFET modules feature a wide input voltage range, fast turn-off during fault conditions, and industry-standard packaging. Typical applications include robotics, broadcast, battery-powered equipment, industrial, and COMM.
