TDK launches high-efficiency ORing modules for industrial and communications applications
TDK Corporation announced the release of its TDK-Lambda i1R series ORing FET modules, designed to enhance power supply redundancy and efficiency across industrial and communications systems.
The new modules support 60A and 80A operation with input voltages up to 60Vdc, replacing traditional diode-based ORing solutions with MOSFET-based technology. This enables higher efficiency of up to 99.5%, while reducing power losses and heat generation.
The i1R series features a fast 500 ns turn-off response to block reverse current during fault conditions, improving system protection. Its compact 1 x 1-inch form factor and low on-resistance simplify thermal management and save board space, while requiring no external components.
Target applications include communications infrastructure, test and measurement equipment, and harsh industrial environments such as robotics, where durability against shock and vibration is critical.
