Operating and Storage Temperature, ALPAC-T SILICON BRIDGE RECTIFIERS ALPAC-1 is a packaging concept designed to replace discrete and stud rectifier arrays offering increased reliability and lower production costs for the customer. ALPAC-T 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 components to temperatures above 300C. 55C to +150. AC AC 50 015 H, -750 235 + .015).147 + .015 THRU HOLE .250 * Max. -500 MAX.
