  • OR's two sources to a single load Low voltage, High current capability Industry-leading ultra-low on-state resistance 99.9% efficient at maximum continuous current No heat sinks or airflow required No de-rating required over full temperature range Fully encapsulate solid state design Internationally patented arrayed MOSFET technology MIL-STD-461E Compliant

POWER-GATE programmable OR’ing diodes  are designed to selectively OR one of two sources to a load.  This configuration can be programmed to automatically conduct current from a pre-defined Master source to the load.  When the primary source drops to a pre-defined low voltage threshold (or alternate metric), the device will “flip,” and current from the secondary Slave source will drive the load.  The customer’s application and performance requirements dictate how the devices will be programmed.  This setup is highly customizable so please contact us so we may assist in configuring devices for your application.   

POWER-GATE programmable OR’ing diodes provide high performance and reliable switching without the conductive losses and leakage typical of Schottky and/or silicon rectifiers.

Conventional silicon and Schottky rectifiers are attractively priced, but have significant performance issues:
• substantial voltage drop as current passes
• conductive losses create significant heat
• batteries never get fully charged
• alternator regulators always inaccurate due to diode drop

Programmable OR’ing diodes are constructed based on our internationally patented large MOSFET array technology and are comprised of two bi-directional solid state relays programmed to respond per the customer’s needs.  See bi-directional relays here.
