SuperFET™ - Super Junction FET Technology

Fairchild's SuperFET™ MOSFET optimizes system efficiency and reliability

SuperFET™ technology minimizes conduction loss and increases switching performance by lowering R_DS(ON) and gate charge (Q_g). This technology is designed to withstand both high-speed voltage (di/dt) and current (dv/dt) switching transients, allowing the devices to operate reliably at higher frequencies. These high-voltage SuperFET MOSFETs address demanding high-voltage, fast-switching applications that require high efficiency. The reliability provided by SuperFET technology is a particularly important benefit in transient-prone applications such as High Intensity Discharge (HID) lighting ballasts and power supplies for Plasma Display Panel (PDP) televisions. The minimization of conduction losses that SuperFETs offer are important to lighting manufactures who increasingly seek ways to conserve energy to meet PFC requirements. Similarly, demanding applications like AC/DC power supplies for plasma TVs rely on designs that offer reliability and efficiency to ultimately lower system costs. [more about SuperFET technology]
