International Rectifier Introduces New Compact Bridge Rectifiers Designed for High-Volume Manufacturing

    EL SEGUNDO, Calif. - International Rectifier today introduced a new series of compact one amp, single-phase, full-wave bridge rectifiers with unique power-to-volume ratios designed to provide greater power density in high-volume, industrial and consumer electronic devices.

    The new DF Series bridge rectifiers are used to convert raw alternating current (AC) into direct current (DC). Typical applications include compact power supplies and battery chargers for cellular phones, notebook computers and other portable and rechargeable devices.

    Vito Bellino, High Power Product Engineer, said, "The new DF Series bridge rectifiers are competitively priced, follow industry-standard pin-outs, and are compatible with commonly used, high-volume assembly methods. Additionally, the small package outline helps increase power density."

    These very compact bridges offer unique power-to-volume ratios with stable operation in a temperature range from -55 to 150 degrees Celsius. The package has high thermal conductivity in an electrically insulated, UL-approved case. The junction-to-case thermal resistance is among the best in the market with 60 degrees Celsius per watt. Maximum repetitive peak reverse voltage range is 50 to 1000 volts.

    The new bridge rectifiers are made with glass-passivated die and encapsulated in either a four-pin thru-hole (D-70) or a surface-mount (D-71) dual in-line package. The thru-hole devices are shipped in tubes, while surface-mount devices are supplied in tape-and-reel.

    The bridge rectifiers are encapsulated with QMFZ2 molding compound, a safe and UL-certified material under class 94V-0.

    Pricing and Availability

    The new DF Series full-wave bridge rectifiers are available immediately. Pricing begins at US $0.42 each in 10,000-unit quantities.
