Best-in-class active OR’ing MOSFET controller from Diodes Incorporated supports power supplies up to 400V

Extending the capability to support redundancy power systems with rail voltages up to ±400V, the ZXGD3112N7 active OR’ing MOSFET controller introduced by Diodes Incorporated, builds on a successful design employed in previous 40V and 200V devices. A low turn-off threshold voltage enables very low R_DS(on) MOSFETs to operate as ideal diodes, providing a highly efficient power system that is well-suited for target applications in telecoms systems, data centers and servers, where OR’ing two or more power supplies together provides redundancy.

Recognizing the trend towards using higher system voltages to raise power distribution efficiency, the ZXGD3112N7 also contributes to increased system reliability, since its use in conjunction with low R_DS(on) MOSFETs allows operation at lower temperatures compared to the alternative of a Schottky-blocking diode. In addition to increasing system efficiency, its turn off threshold voltage of
