GreenBridge™ Series of High-Efficiency Bridge Rect

ON Semiconductor's GreenBridge active bridge quad-MOSFETs lower conduction losses and improve power conversion efficiency in a smaller form factor for high-power PoE applications. The FDMQ8205 family is comprised of two N-channel and two P-channel 80 V rated MOSFETs in a single, small MLP 12 package.

With improved conduction loss and superior efficiency compared to a conventional Schottky bridge, GreenBridge solutions provide up to 10 times better power dissipation. A novel, self-driving technique eliminates the need for external drive components which reduces solution size, cost, and complexity in active bridge applications.
