SEMTECH CORPORATION 652 Mitchell Road, Newbury Park, California 91320 (805) 498-2111, (213) 628-5392 / TWX: 910-336-1264 ALPAC, SILICON BRIDGE RECTIFIERS Semtech Corporation introduces ALPAC a complete line of Single Phase Silicon Bridge Rectifier circuits. Designed in Aluminum Cases to provide maximum thermal conductivity and simple installation. ALPAC universal terminals, insulated from case, provide a 3 way electrical connection: fast disconnect, wire wrap around and hole wire insert for soldering. Internally the device utilizes the Semtech high performance solid double heat sink junc- tions designed for mechanical strength and eliminating the use of solders for improved reliability. The bridges are designed for utilization in power supplies, AC to DC converters and motor control circuits. Sine : VF Wave Average DC Max.
