A module changes how power systems work, cuts heat, stops faults fast, and keeps backup power running in parallel and redundant setups.
TDK Corporation has introduced the TDK-Lambda i1R ORing FET modules, capable of operating at 60 A or 80 A with a maximum input voltage of 60 Vdc. These ORing modules are designed to replace traditional diodes in applications that require ORing functionality for power supply redundancy or parallel operation. The i1R series uses MOSFET-based circuitry to deliver improved performance while reducing reverse current transients.
The modules feature a fast turn-off response of 500 ns (typ), blocking reverse current transients during fault conditions for improved protection. They have a low on-resistance of 2.5 mΩ and 1.5 mΩ, reducing power losses and heat, which simplifies thermal design. The modules come in a shielded metal package measuring 1 x 1 inch (26.3 x 26.3 mm), saving board space and supporting efficient cooling. In addition, the series operates without the need for external components, simplifying implementation.
Applications for the i1R modules include communications systems, test and measurement equipment, and industrial or robotics environments that require high resistance to shock and vibration. While the i1R series was designed to complement other TDK-Lambda solutions, including the i7A and i7C non-isolated converters, GQA and HQA industrial isolated DC-DC converters for high shock and vibration environments, and RGF differential mode filter modules, its flexible architecture also allows it to be used alongside other power solutions.
Some of the key features of the TDK-Lambda i1R ORing FET modules include:
- 99.5% efficiency
- Compact size
- Fast turn-off during fault conditions
- Replaces traditional diodes
Main applications include communications, test and measurement, and harsh environment industrial and robotics systems that require a high degree of shock and vibration.
