Compact Bridge Rectifiers

The new DF series of compact, one amp, single-phase, full-wave bridge rectifiers is designed to provide greater power density in high-volume, industrial and consumer electronic devices. Typical applications include compact power supplies and battery chargers for cellular phones, notebook computers and other portable and rechargeable devices.

The series are compatible with all standard PC board assembly and soldering techniques. Soldering can be done below 245°C to minimize solder oxidation without losing meniscus and fillet formation. The rectifiers are also suitable for high temperature soldering (250-260°C for 8-10 seconds). These compact bridges offer power-to-volume ratios with stable operation in a temperature range from -55 to +150°C. The package has high thermal conductivity in an electrically insulated, UL-approved case. The junction-to-case thermal resistance is 60°C per watt. Maximum repetitive peak reverse voltage range is 50 to 1000 volts.

The 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 designed for input circuits in industrial and consumer equipment. The compact packaging is especially useful for power supplies and battery chargers for cellular phones, notebook computers and other portable and rechargeable electronic devices.

They are encapsulated with QMFZ2 molding compound, UL-certified under class 94V-0. All materials used in the DF family are non-toxic and environmentally friendly. Moreover, no CFC compounds are used during any stage of the manufacturing process.
