Better Efficiency Rectifier

System

Ultra Efficient, High Speed Diode

The NIS6111 ORing diode is a high speed, high efficiency, hybrid

rectifier, designed for low voltage, high current systems, such as

those required for today’s digital circuits. It couples a high speed

integrated circuit with a power MOSFET to create a diode with the

same forward drop characteristics as a MOSFET. It offers increased

efficiency for switching power supplies as well as in ORing diode

applications.

It offers a low on resistance that can be further reduced by the

addition of external MOSFETs. It features the highest reverse

recovery speed of any device in the industry.

Features

• Low Forward Drop Improves System Efficiency

• Ultra High Speed

• Can be used in High Side and Low Side Configurations

• 24 V Rating

• Allows use of External MOSFETs for Extended Current Handling

Capacity

Applications

• Redundant Power Supplies for High−Availability Systems

• Static ORing Diodes

• Low Voltage, Isolated Outputs

• Flyback, Forward Converter, Half Bridge Converters
