SEMTECH CORPORATION 652 Mitchell Road, Newbury Park, California 91320 (805) 498-2111, (213) 628-5392 / TWX: 910-336-1264 ALPAC - R50 SILICON BRIDGE RECTIFIERS ALPAC-R50 is a packaging concept designed to replace discrete and stud rectifier arrays offering increased reliability and lower production costs for the customer. ALPAC-R50 utilizes the Metoxilite hermetically sealed rectifier--NASA and MIL approved rectifiers available. Internal components are supported in a low thermal impedance, epoxy thermoset- filled high alumina ceramic. This construction firmly secures and insulates the internal com- LU wl rear t ponents to temperatures above 300C. ALPAC-R50 is designed for utilization in power + supplies, AC to DC converters, motor control circuits, etc. a = BRIDGE RECTIFIERS AC , SCBKOS x SCBK1 SCBK2 SCBK3 Bie [=] 50 MAX. SCBK4 [2] !
